顯示裝置…對面材係'表面材(成為保護板的透明面材)與背 面材（顯示元件）’且密封部形成用硬化性樹脂組成物及樹脂 層形成用硬化性樹脂組成物係光硬化性樹脂組成物的實施 形態進行說明。 &lt;顯示裝置&gt; 第1圖係本實施形態的顯示裝置一例之剖視圖，第2圖 係平面圖。 顯示裝置1係具有：透明面材10(第2面材（或第1面 材））、顯示元件50(第1面材（或第2面材)）、樹脂層4〇、密封 部42、可撓性印刷電路板54(FPC)、及遮光印刷部55(遮光 部），該透明面材10係屬於表面材，該顯示元件50係屬於背 面材，該樹脂層40係由透明面材1〇與顯示元件5〇所包夾， 名进'封部42係包圍著樹脂層40的周圍，該可撓性印刷電路 板54係連接於顯示元件5〇且搭載有使顯示元件50啟動之驅 動1C ’該遮光印刷部55係形成於透明面材1〇的周緣部。 _示裝置1中，在透明面材10的周緣部設置遮光印刷部 55 ’且由遮光印刷部55所包圍的透光部56之面積小於由密 201206701 封°M2所包圍的樹脂層40之面積，透明面材ι〇的面積係大 於員示元件50的面積’樹脂層40與密封部42的合計面稽 ' 才 10 顯示元件50的各面積。 [表面材] 表面材係顯示元件之顯示影像能穿透過的 (保護板）。 透明面材係可舉例如玻璃板、或透明樹脂板就對來 Γ、_件的出射光與反射光呈高透明性的觀點，當然亦 j具有耐光性、低雙折射性、高平面精度、耐表面到傷性 问機械強度等觀點’最佳為玻璃板。就為使光硬化性樹 組成物進行硬化的光能充分穿透之觀點，亦是以玻璃板^ 佳。 玻璃板的材料係可舉例如鈉弼玻璃等玻璃材料，較佳 係鐵份更低、偏錄少的高？透玻璃（晃«)。為提高安全 性，表面材亦可使用強化玻璃。 透明樹脂板的材料係可舉例如透明性高的樹脂材料 (諸如聚碳酸酯、聚曱基丙烯酸甲酯等）。 在透明面材中，為提升與樹脂層間之界面接著力，亦 可施行表面處理。表面處理的方法係有如：對透明面材之 表面利时錢合難行纽的方法、或者彻由火焰燃 燒益所產生的氧化火燄形成氧化矽薄膜的處理等。在透明 面材上，為提高顯示影像的對比，亦可在與樹脂層間的接 合面之背面設置抗反射層。抗反射層係可利用諸如在透明 面材的表面上直接形成無機薄膜的方法、或將設有抗反射 201206701 層的透明樹脂薄膜貼合於透明 面材上的方法而進行設置。 再者配。衫像顯示之目的透明面材之一部分或全 體亦可預先施行著色'或呈毛破璃狀*使光散射或利用 表面的細微凹凸等而使穿透時的光折射或反射。又，亦可 將如上述㈣的光學膜、偏域等進行光學調變的光學膜 等經貼合於透明面材上形成—體物，使用為透明面材。 透明面材的厚度，就機械強度、透明性的觀點，當屬 玻璃板時通常為0.5〜25mm。在室内使用的電視接收器、pc 用顯示器等用途上，就顯示裝置的輕量化觀點，較佳為 0_7〜6mm ’而設置於室外的大眾顯示用途時，較佳為 3〜20mm。透明面材係可使用強化玻璃，當透明面材較薄時 便可使用化學強化玻璃。透明樹脂板的情況較佳係 2〜10mm。 [背面材] 背面材係顯示元件。 圖示例的顯示元件50係將設有彩色濾光片的透明面材 52、與設有TFT的透明面材53進行貼合，再將其利用一對偏 光板51夹持而構成的液晶顯示元件一例，但本實施形態的 顯示元件並不侷限於圖示例。 顯示元件係在至少其中一者為透明電極的一對電極 中’挾持利用外部之電氣信號而變化光學樣態的顯示材。 依照顯示材的種類，有諸如：液晶顯示元件、EL顯示元件、 電漿顯示元件、電子墨水型顯示元件等。又，顯示元件係 具有貼合一對面材且該一對面材至少一者為透明面材的構 12 201206701 ’並配置成透明面材側鄰接於樹脂層。此時，部分的顯 示元件係在與樹脂層相鄰側的透明面材最外層側，設置諸 如偏光板、相位差板等光學膜。此情況，樹脂層係呈顯示 元件上的光學膜與表面材相接合的樣態。 對顯示元件與樹脂層的接合面，為提升與密封部間之 界面接著力，亦可施行表面處理。表面處理係可僅對周緣 部施行，亦可對面材的整體表面實施。表面處理的方法有 如利用可低溫加工的接著用底漆等施行處理之方法等。 顯示元件的厚度係當屬於利用TFT啟動的液晶顯示元 件時’通常為0.4〜4mm，當屬於EL顯示元件時通常為 0_2〜3mm.。 [樹脂層] 樹脂層係由本發明的硬化性樹脂組成物（以下亦稱「樹 脂層形成用光硬化性樹脂組成物」）進行硬化而構成的層。 本發明的硬化性樹脂組成物（本實施形態的樹脂層形 成用光硬化性樹脂組成物），係可降低硬化後的彈性模數， 並可降低進行硬化時所產生的應力。所以，可抑制因該應 力對顯示元件的顯示性能造成不良影響。又，該硬化性樹 脂組成物在未硬化時的黏度低，所以能在短時間施行對面 材表面的硬化性樹脂組成物供應，因而容易防止在表面材 與背面材層積後出現氣泡殘留情形。 樹脂層的厚度較佳係〇_〇3〜2mm、更佳係〇.1〜〇.8mm、 特佳係0.2〜0.6mm。若樹脂層的厚度達〇 〇3mm以上，樹脂 層便可有效的緩衝因來自透明面材側的外力所造成衝擊 13 201206701 等，俾可保護顯示元件元件。特別係當顯示元件對外力屬 於敏銳，較容易影響顯示品質的情況，較佳係設成達〇 以上的厚度。又，本實施形態的製造方法中，即便在透明 面材與顯示元件之間混入超越樹脂層厚度的異物，樹脂層 的厚度仍不會有太大的變化，對光穿透性能的影響較少。 若樹脂層的厚度在2mm以下，在樹脂層中不易殘留氣泡， 且顯示裝置的整體厚度不會成為多餘的厚^當樹脂層的彈 性模數小之情況，為抑制顯示元件經時性接合位置偏移等 情形，較佳係設為〇.6mm以下的厚度。 調整樹脂層厚度的方法，係有如調節後述密封部的厚 度，且同時調節對第1面材所供應之液狀樹脂層形成用光硬 化性樹脂組成物的供應量之方法。 [密封部] 密封部係塗佈後述液狀密封部形成用光硬化性樹脂組 成物，經硬化而構成者。因為顯示元件的影像顯示區域之 外側區域比較狹窄，因而密封部的寬度以狹窄為宜。密封 部的寬度較佳係0.5〜2mm、更佳係〇 8〜丨6mm。 [遮光印刷部] 視需要，可在透明面材的周緣部設置遮光印刷部。遮 光印刷部係依顯示元件的影像顯示區域之外均無法從透明 面材側看到的方式，隱藏連接於顯示元件的配線構件等。 遮光印刷部係可設置於透明面材與樹脂層的接合面、或其 背面’就降低遮光印刷部與影像顯示區域的視差之觀點， 以設置於透明面材與樹脂層的接合面為佳。當透明面材係 14 201206701 玻璃板的情況，若遮光印刷部係使用含黑色顏料的陶瓷印 刷，則遮光性高而屬較佳。藉由將表面或背面已設有遮光 印刷部的透明薄膜貼合於透明面材上，亦可形成遮光印刷 部。亦可使用沒有遮光印刷部的透明面材。 [形狀] 顯示裝置的形狀通常係矩形。 顯示裝置的大小並無特別的限定，因為本實施形態的 製造方法特別適用於較大面積之顯示裝置的製造，因而當 屬於採用液晶顯示元件之情況，以pc螢幕的情況而言較佳 為0.3mx〇.18m，以電視接收器的情況而言較佳為0.4mx〇.3m 以上、更佳為0.7mx〇.4m以上。顯示裝置的大小上限大多係 依照顯示元件的大小而決定。又，過大的顯示裝置在設置 等處理上容易趨於困難。顯示裝置的大小上限係從該等限 制觀之，通常為2.5mx 1.5m程度。小型顯示器的情況，較佳 為 0.14mx〇.08m 以上。 成為保護板的透明面材、與顯示元件的尺寸係可為大 致相等，但就與收納顯示裝置的其他框體間之關係，多數 情況係透明面材較顯示元件大一圈。又，相反的依照其他 框體的構造，亦可使透明面材若干小於顯示元件。 &lt;顯示裝置之製造方法&gt; 本實施形態的顯示裝置之製造方法，係包括有下述步 驟(a)〜(d)的方法。 (a)在第1面材（背面材（或表面材))的表面周緣部，塗佈 含有硬化性化合物⑴及光聚合起始劑（C1)的液狀密封部形 15 201206701 成用光硬化性樹脂組成物，而形成未硬化密封部的步驟 (但，當第1面材係顯示元件的情況，便在影像顯示側的表 面上形成密封部）。 (b) 對未硬化密封部所包圍的區域，供應含有硬化性化 合物(II)與光聚合起始劑(C2)的液狀樹脂層形成用光硬化性 樹脂組成物之步驟。

In the preferred embodiment of the present invention, the laminated system display device of the present invention is used for the surface material "surface material (transparent surface material to be a protective sheet) and back surface material (display element)" and the sealing portion is formed to have curability. An embodiment in which the resin composition and the curable resin composition for forming a resin layer are photocurable resin compositions will be described. &lt;Display Device&gt; Fig. 1 is a cross-sectional view showing an example of the display device of the embodiment, and Fig. 2 is a plan view. The display device 1 includes a transparent surface material 10 (a second surface material (or a first surface material)), a display element 50 (a first surface material (or a second surface material)), a resin layer 4A, a sealing portion 42, a flexible printed circuit board 54 (FPC) and a light-shielding printing unit 55 (light-shielding portion) belonging to a surface material, the display element 50 being a back surface material, and the resin layer 40 being a transparent surface material 1 The 〇 and the display element 5 are sandwiched, and the enclosing portion 42 surrounds the periphery of the resin layer 40. The flexible printed circuit board 54 is connected to the display element 5 and is mounted with a driving for driving the display element 50. 1C 'The shading printing portion 55 is formed on the peripheral portion of the transparent surface material 1〇. In the display device 1, the light-shielding portion 55' is provided on the peripheral portion of the transparent surface material 10, and the area of the light-transmitting portion 56 surrounded by the light-shielding portion 55 is smaller than the area of the resin layer 40 surrounded by the seal 20120601. The area of the transparent face material ι is larger than the area of the member element 50 'the total surface of the resin layer 40 and the sealing portion 42'. 10 The area of the element 50 is displayed. [Surface material] The surface material shows the display image of the component that can pass through (protective plate). The transparent surface material is, for example, a glass plate or a transparent resin plate, and has high transparency to the emitted light and the reflected light of the Γ, and, of course, has light resistance, low birefringence, and high planar precision. From the viewpoint of resistance to surface to mechanical strength, etc., the best is glass plate. In view of the fact that the light energy for hardening the photocurable tree composition is sufficiently penetrated, it is also preferable to use a glass plate. The material of the glass plate may be, for example, a glass material such as sodium bismuth glass, and is preferably higher in iron content and less in partial recording. Through the glass (shaking «). For safety, tempered glass can also be used for the surface material. The material of the transparent resin sheet may, for example, be a resin material having high transparency (such as polycarbonate, polymethyl methacrylate or the like). In the transparent face material, surface treatment can also be performed in order to enhance the adhesion between the resin layer and the resin layer. The surface treatment method is, for example, a method of making the surface of the transparent surface material profitable, or a treatment for forming a ruthenium oxide film by an oxidizing flame generated by flame combustion. In order to improve the contrast of the display image on the transparent surface material, an antireflection layer may be provided on the back surface of the joint surface with the resin layer. The antireflection layer can be provided by, for example, a method of directly forming an inorganic thin film on the surface of a transparent face material, or a method of laminating a transparent resin film provided with an antireflection 201206701 layer on a transparent face material. In addition, match. A part or the whole of the transparent surface material for the purpose of display of the shirt may be preliminarily colored or light-grained* to scatter or reflect the light at the time of penetration by using light scattering or fine unevenness of the surface. Further, an optical film or the like which is optically modulated by an optical film or a bias field as in the above (4) may be bonded to a transparent surface material to form a body material, and may be used as a transparent surface material. The thickness of the transparent face material is usually 0.5 to 25 mm in terms of mechanical strength and transparency. In the case of a television receiver or a pc display used indoors, it is preferably 3 to 20 mm in terms of weight reduction of the display device, preferably 0_7 to 6 mm', and for outdoor display use. Reinforced glass can be used for the transparent surface material, and chemically strengthened glass can be used when the transparent surface material is thin. The case of the transparent resin sheet is preferably 2 to 10 mm. [Back material] The back material is a display element. The display element 50 of the illustrated example is a liquid crystal display in which a transparent surface material 52 provided with a color filter and a transparent surface material 53 provided with a TFT are bonded together and sandwiched by a pair of polarizing plates 51. Although an element is an example, the display element of this embodiment is not limited to the illustration. The display element is in a pair of electrodes in which at least one of the electrodes is a transparent electrode. A display material that changes an optical state by an external electrical signal is held. Depending on the type of the display material, there are, for example, a liquid crystal display element, an EL display element, a plasma display element, an electronic ink type display element, and the like. Further, the display element has a structure in which a pair of face materials are bonded and at least one of the pair of face materials is a transparent face material, and the transparent face material side is disposed adjacent to the resin layer. At this time, a part of the display elements are provided on the outermost layer side of the transparent face material on the side adjacent to the resin layer, and an optical film such as a polarizing plate or a phase difference plate is provided. In this case, the resin layer is in a state in which the optical film on the display element is bonded to the surface material. The surface of the joint between the display element and the resin layer may be subjected to surface treatment in order to enhance the adhesion between the sealing member and the sealing portion. The surface treatment can be applied only to the peripheral portion or to the entire surface of the face material. The surface treatment method is, for example, a method which can be processed by a low temperature process followed by a primer or the like. The thickness of the display element is usually 0.4 to 4 mm when it belongs to a liquid crystal display element activated by a TFT, and is usually 0 to 3 mm when it belongs to an EL display element. [Resin layer] The resin layer is a layer formed by curing the curable resin composition of the present invention (hereinafter also referred to as "photocurable resin composition for forming a resin layer"). The curable resin composition of the present invention (the photocurable resin composition for forming a resin layer of the present embodiment) can reduce the modulus of elasticity after curing and can reduce the stress generated during curing. Therefore, it is possible to suppress the adverse effect on the display performance of the display element due to the stress. Further, since the curable resin composition has a low viscosity when it is not cured, the supply of the curable resin composition to the surface of the surface material can be performed in a short period of time, so that it is easy to prevent the occurrence of air bubbles remaining after the surface material and the back surface material are laminated. The thickness of the resin layer is preferably 〇_〇3 to 2 mm, more preferably 11 to 〇8 mm, and particularly preferably 0.2 to 0.6 mm. If the thickness of the resin layer is more than mm3 mm, the resin layer can effectively buffer the impact caused by the external force from the side of the transparent surface material. 13 201206701, etc., can protect the display element components. In particular, when the display element is sensitive to external forces and is more likely to affect the display quality, it is preferably set to a thickness greater than or equal to 〇. Further, in the production method of the present embodiment, even if a foreign material exceeding the thickness of the resin layer is mixed between the transparent surface material and the display element, the thickness of the resin layer does not change much, and the light penetration property is less affected. . When the thickness of the resin layer is 2 mm or less, bubbles are less likely to remain in the resin layer, and the overall thickness of the display device does not become excessively thick. When the elastic modulus of the resin layer is small, the position of the display element is suppressed over time. In the case of offset or the like, it is preferably set to a thickness of 〇.6 mm or less. The method of adjusting the thickness of the resin layer is a method of adjusting the supply amount of the liquid-hardenable resin composition for forming a liquid resin layer supplied to the first face material by adjusting the thickness of the sealing portion to be described later. [Sealing portion] The sealing portion is formed by applying a photocurable resin composition for forming a liquid sealing portion, which is described later, and is cured. Since the outer region of the image display area of the display element is relatively narrow, the width of the sealing portion is preferably narrow. The width of the sealing portion is preferably 0.5 to 2 mm, more preferably 8 to 6 mm. [Light-shielding printing portion] A light-shielding printing portion can be provided on the peripheral portion of the transparent surface material as needed. The opaque printing unit hides the wiring member or the like connected to the display element so that it cannot be seen from the side of the transparent surface material except for the image display area of the display element. The light-shielding printing portion can be provided on the joint surface of the transparent surface material and the resin layer or the back surface thereof to reduce the parallax between the light-shielding printing portion and the image display region, and is preferably provided on the joint surface of the transparent surface material and the resin layer. In the case of a transparent surface material, in the case of a glass plate, if the blackout pigment is used as the blackout pigment, the light-shielding property is high and it is preferable. The light-shielding printing portion can also be formed by bonding a transparent film having a light-shielding printing portion on the front or back surface to the transparent surface material. A transparent face material without a light-shielding printing portion can also be used. [Shape] The shape of the display device is usually rectangular. The size of the display device is not particularly limited, and the manufacturing method of the present embodiment is particularly suitable for the manufacture of a display device having a large area. Therefore, in the case of using a liquid crystal display element, it is preferably 0.3 in the case of a pc screen. The mx 〇.18 m is preferably 0.4 mx 〇.3 m or more, and more preferably 0.7 mx 〇.4 m or more in the case of the television receiver. The upper limit of the size of the display device is often determined in accordance with the size of the display element. Further, an excessively large display device tends to be difficult in processing such as setting. The upper limit of the size of the display device is determined from these limits, typically about 2.5 m x 1.5 m. In the case of a small display, it is preferably 0.14 mx 〇.08 m or more. The transparent surface material to be the protective sheet and the size of the display element can be substantially equal, but in many cases, the transparent surface material is larger than the display element in a relationship with other housings accommodating the display device. Further, contrary to the configuration of the other housings, the transparent surface material may be made smaller than the display elements. &lt;Manufacturing Method of Display Device&gt; The method of manufacturing the display device of the present embodiment includes the following steps (a) to (d). (a) Applying a liquid seal portion containing a curable compound (1) and a photopolymerization initiator (C1) to the peripheral surface portion of the surface material (or surface material) of the first surface material (2012) The resin composition is a step of forming an uncured seal portion (however, when the first face material is a display element, a seal portion is formed on the surface on the image display side). (b) A step of supplying a photocurable resin composition for forming a liquid resin layer containing a curable compound (II) and a photopolymerization initiator (C2) to a region surrounded by the unhardened seal portion. (c) In the decompression environment of 100 Pa or less, the resin layer is formed by photocuring; the M. lunar composition is superposed on the second face material (surface material (or back material)) to obtain a resin layer. a step of laminating a precursor of the photocurable resin composition which has been sealed by the i-th face material, the second face material, and the uncured seal portion (however, when an anti-reflection film is provided on the surface of the second face material) In the case where the surface material of the second surface material is the display element, the photo-curable resin for forming the resin layer is adjacent to the image display side. The way the composition overlaps). (d) A step of curing the uncured seal portion and the resin layer-forming photocurable resin composition by subjecting the laminated precursor to a pressure of 50 kPa or more. When the light-shielding portion is not formed on the transparent surface material, the sealing portion and the resin layer-forming photocurable resin composition are irradiated with light from the transparent surface material side of the laminated precursor through the light transmitting portion. When the light shielding portion is formed on the peripheral portion of the transparent surface material, the area of the light transmission portion surrounded by the light shielding portion is smaller than the area of the resin layer surrounded by the sealing portion, and the resin layer is formed of a photocurable resin. In the absorption wavelength region (λ2) of the photopolymerization initiator (C2), the absorption wavelength of the photopolymerization initiator (C1) contained in the photocurable resin composition for forming the seal 16 201206701 The region (λΐ) exists on the longer wavelength side, and the light irradiated from the side of the laminated precursor in the above step (d) covers the wavelength light and the absorption wavelength region (λ2) in the absorption wavelength region (λ1). The wavelength of light inside. In the production method of the present embodiment, the liquid curable resin composition for forming a liquid resin layer is sealed between the second surface material and the second surface material in a pressure-reduced environment. The resin layer to be sealed is formed by a method in which a photocurable resin composition is cured to form a resin layer (decompression lamination method). The method of encapsulating the photocurable resin composition for forming a resin layer under reduced pressure is not a method of injecting a photocurable resin for forming a resin layer in a narrow space between the first surface material and the second surface material. The photocurable resin composition for forming a resin layer is supplied to the entire surface of the first surface material, and then the second surface material is superposed on the surface of the first surface material and the second surface material. A method of resin composition. An example of a method for producing a transparent laminate by encapsulating a photocurable resin composition for forming a liquid resin layer under reduced pressure and curing the photocurable resin composition for forming a resin layer under atmospheric pressure known. For example, the method for producing a transparent laminate described in the pamphlet of International Publication No. WO 2008/81838, the pamphlet of International Publication No. 2009/16943, and the photocurable resin composition used in the production method are incorporated in the present specification. [Step (a)] First, an uncured seal portion is formed along the peripheral portion of the surface of the first face material. The first surface material can be used arbitrarily as a back material or a surface material. 17 201206701 When the first surface material is transparent to the protective sheet serving as the display element, the surface forming the uncured seal portion can be arbitrarily two of the two surfaces. When the properties of the two surfaces are different, the desired one is selected - for example, when one of the surfaces has a surface treatment of the interface between the coating and the resin layer, an uncured seal is formed on the surface. In addition, in the case where an anti-reflection layer is provided on one of the surfaces, it is hardened in the back and the field. 〜 When the first surface material display element is not formed, the surface on which the uncured seal portion is formed is the surface on the image display side. An unhardened sealing portion is mainly characterized in that, in the step (c) described later, the composition of the photocurable resin layer having a liquid crystal resin layer is not formed from the interface between the first surface material and the first surface material. The interface between the hardened seal portion and the second face material door and the surface is more than or equal to the degree of adhesion, and the degree of robustness is maintained. Therefore, it is preferable that the uncured seal portion is formed of a photocurable resin composition having a high viscosity = a seal portion, and is applied by, for example, printing, dispensing, or the like. In addition, in order to maintain the space between the first surface material and the second surface material, it is also possible to form a photocurable resin for forming a spacer particle having a predetermined particle diameter in the photocurable resin composition for sealing portion formation. Immediately after application of the composition, the sealing portion may be partially semi-cured by irradiating light for curing the sealing portion, and the shape of the sealing portion may be maintained for a longer period of time. [Photocurable resin composition for sealing portion formation] The photocurable resin composition for sealing portion formation (hereinafter referred to as "sealing 201206701 material") contains a sclerosing curable compound (1) and a photopolymerization initiator (ci) Liquid composition. The viscosity of the photocurable resin composition for forming the sealing portion is preferably 5 〇〇 to 3 _Pa · s, more preferably fine 〇 测 测 测 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 If the viscosity is 500 Pa·s or more, the shape of the uncured seal portion can be maintained for a long time, and the height of the seal portion can be sufficiently maintained. If the viscosity is (4)·s or less, the sealing portion can be formed by a coating method. The viscosity of the photocurable resin composition for forming the seal portion was measured by using an E-type viscometer. (The curable compound (I)) The curable compound (1) is preferably one or more types of oligomers (VIII), and it is preferable to adjust the viscosity of the photocurable resin composition for sealing a portion to be within the above range. More than one type of the monomer (8), the oligomer (4) has a curable group and the number average molecular weight is a tetrahedral surface; the monomer (B) has a curable group and has a molecular weight of 25 to 6 Å. The curable group of the oligomer (A) or the monomer (8) may, for example, be an addition polymerizable unsaturated group (such as an acryloxy group, a fluorenyl group, or the like), an unsaturated group and a thiol group. The combination of the groups and the like is preferably selected from the group consisting of a propoxy group and a mercaptopropenyloxy group from the viewpoint of a sealing portion having a high curing speed and high transparency. The curable group in the polymer (A) and the curable group in the monomer (B) may be the same or different. Since the higher molecular weight oligomer (8) is more normalized, the bio-reactive valley tends to become lower than the hardening I·gene in the lower molecular weight monomer (B), and the hardening of the monomer (8) proceeds first. This leads to an increase in the viscosity of the composition of the 201206701 body, which makes the hardening reaction inhomogeneous. In order to reduce the reactivity of the hardening group, the hydrazine can obtain a homogeneous sealing portion. It is preferable to set the hardening group in the polymer (Α) to a highly reactive propylene oxide group, and The hardening group in the body (Β) is a methacryloxy group having a low reactivity. The number average molecular weight of the oligomer (Α) is 3〇〇〇〇~丨〇〇〇〇〇, preferably 40,000 to 80,000, more preferably 50,000 to 65,000. When the average molecular weight of the oligo (Α) is within this range, it is easier to adjust the viscosity of the photocurable resin composition for sealing portion formation within the above range. The number average molecular weight of the polymer (Α) is obtained by measurement of Gpc and is a polystyrene-equivalent number average molecular weight. In addition, Gpc = centering, when there is a spike of unreacted low molecular weight components (monomers, etc.), the peak is excluded to obtain a number average molecular weight. The molecular weight of the monomer (B) is 125 to 6 Å, preferably 14 Å to 4 Å, more preferably 150 to 350. When the molecular weight of the monomer (B) is at least 125, the volatilization of the monomer (9) can be suppressed when it is produced by a reduced pressure layering method described below. When the molecular weight of the material (B) is _ or less, the solubility of the monomer (8) to the high molecular weight oligomer (4) can be improved, and the viscosity of the photohardenable resin composition for forming a sealing portion can be appropriately adjusted.

It can be synthesized 'but it is still difficult to mix with the monomer. Therefore, it is preferable to directly synthesize the obtained product into a seal after synthesizing the carbamate conjugate (A1) according to the synthesis method using the monomer (B) (the following monomers (B1) and (B2)).

The oxygen-extended ethyl structure can be present in the polyoxy-extension propyl polyol molecule in a random or block form. Further, the oxygen-extended ethyl structure may be internal to the polyoxy-extension propyl polyol molecule or just before the terminal hydroxyl group. When the oxygen-extended ethyl structure is located just before the terminal hydroxyl group, it can be obtained by adding an epoxy bake in the oxygen-extended propyl polyol.

The resin layer is filled with the photocurable resin composition, and the second surface material and the second surface material are separated by a predetermined interval (that is, the resin layer is a predetermined thickness). In this case, it is preferable to consider the volume reduction due to the hardening shrinkage of the photocurable resin composition for forming a resin layer. Therefore, the amount is preferably a thickness of the photocurable resin composition for forming a resin layer, and a certain amount is thicker than a predetermined thickness of the resin layer. When the hardening shrinkage is small, the predetermined thickness of the resin layer and the thickness of the photocurable resin composition for forming a resin layer may be made substantially equal. The supply method is a method in which the first surface material is laid flat and supplied in a dot shape, a line shape or a surface shape by means of a supply means such as a dispenser or a mold coater. [Photocurable resin composition for forming a resin layer] The photocurable resin composition for forming a resin layer has a storage shear modulus of 5 χ 102 〜 lxl 〇 5 Pa and a loss tangent at the time of dynamic viscoelasticity measurement after curing ( A liquid photocurable resin composition having a tan (5) of 1.4 or less. The method for measuring the storage shear modulus and loss tangent is as described in detail later, using a dynamic viscoelasticity measuring device for an uncured resin. A method of curing a resin composition by applying a dynamic shear stress to a layer forming photocurable resin composition while applying a dynamic shear stress. When the shear modulus after curing is 5 xi 〇 5 Pa or less, the hardening can be sufficiently reduced. When the stress of the resin shrinks, 俾 can suppress the influence on the display quality of the display panel 27 201206701. If the shear elastic modulus is 5 xi Q 2 or more, the elastic deformation of the resin layer is less likely to occur, and the display element can be easily prevented from being transparent. The position of the lunar material is offset by X. If the loss tangent is below 丨4, the display element can be sufficiently fixed on the transparent surface material even if the display device is vertically ax. The deformation of the display element may be prevented from occurring due to plastic deformation of the resin layer due to the self-weight of the display element, etc. The storage shear modulus is preferably 8xl〇2~5xl〇4pa' It is preferable that the loss tangent is preferably 〇 or less, and more preferably 〇5 or less. The IPS type liquid crystal display element described later is easy to use stress due to shrinkage when the resin layer is cured. The place where the display element affecting the display performance is preferably a liquid photocurable resin surface material having a storage shear elastic modulus of 5 x 1 〇 2 to 5 X 103 Pa and a loss tangent (tar ^) of less than 0.2 after hardening. By setting the shear modulus to 5x10Pa or less, the stress caused by shrinkage of the resin during hardening can be sufficiently lower than the smaller value, and even if the loss tangent (tanS) is less than 0_2, even shearing The resin layer having a low modulus of elasticity can suppress the plastic deformation of the resin layer over time due to the self-weight of the display element. In this case, the loss tangent (tanS) is preferably 0.1 or less. The lower limit of the loss tangent is not Special limited In the case of a softer resin layer, it is usually 0.01 or more. The viscosity of the photocurable resin composition for resin layer formation is preferably 〇' 〇 5 to 50 Pa·s, more preferably When the viscosity is 0.05 Pa·s or more, the ratio of the monomer (B1) to be described later can be suppressed, and the physical properties of the resin layer can be suppressed from being lowered. Further, since the low-boiling component is small, it is suitable for use in a later-described manner. Decompression lamination 28 201206701 Method. If the viscosity is 50 Pa.SJ^, the resin layer is less likely to have bubbles remaining. The viscosity of the photocurable resin composition for resin layer formation is under 25, and it is measured using an E-type viscometer. . The photocurable resin composition for forming a resin layer is preferably a liquid composition and contains a photocurable curable compound ("), a photopolymerization initiator (4), and a non-curable oligomer (9). The oligomer (9) is a curable compound (5) which is cured when the resin layer forming photocurable resin composition is cured, and undergoes a curing reaction and contains an oligomer having two hydroxyl groups per molecule. When the photocurable resin composition is formed to contain the non-curable oligomer (D), the sap of the storage layer can be reduced while suppressing the cleavage of the fat layer (4)), so that the dynamic viscosity can be simultaneously achieved. The bombs are set to t, and the shear elastic modulus and the loss tangent (4) are stored respectively. Further, by using a small amount of the chain transfer agent, the molecular weight of the cured resin layer can be adjusted to lower the storage elastic modulus of the resin layer. However, in many cases, the hardening rate is slowed down. &quot;3 There are many photocurable resin compositions for forming a resin layer of the non-hardening oligomer (9) of the present invention 'Because the content of the oligomer (9) can be used to adjust the elasticity The modulus is therefore preferably reduced by the amount of the chain transfer agent or not. Specifically, 'total of the hardening compound (clear body, silk (A,) and single _') _ mass parts 'chain transfer The amount of the agent to be added is preferably less than 0 parts by mass, more preferably less than 0 to 5 parts by mass.

At least one of the curable compounds is a compound (Ila) having a hydroxyl group which does not react when the photocurable resin composition for forming a resin layer is cured. The curable compound (II) contains the compound (Ila) The cured group having a curing reaction by the curable compound (II) is provided with a radical. The presence of the radical is stable to the non-curable oligomer in the photocurable resin composition for forming a resin layer. Contribution. The compound (Ila) having a radical which does not react upon hardening can be used as long as it has an unreacted hydroxyl group after the hardening reaction, for example, even if a part of the hydroxyl group of the compound (Ila) is hardened, the other part is not When the curing reaction is carried out and remains in an unreacted state, the compound (IIa) having a hydroxyl group which does not react during curing may be a curable group which contributes to the curing reaction and may have a hydroxyl group.

The curable group in the oligomer (A') and the curable group in the monomer (A) may be the same or different from each other. Because of the hardening group of the oligomer having a relatively high molecular weight (A,), the reactivity is more likely to become lower than the hardening group in the monomer (B,) having a lower molecular weight, and thus the hardening of the monomer (B,) It will be carried out first, resulting in an increase in the viscosity of the composition as a whole, and there may be a possibility that the hardening reaction is heterogeneous. In order to reduce the reactivity of the curable groups, the homogeneous resin layer may be obtained, and the curable group in the oligomer (A,) is preferably a highly reactive propylene oxy group, and The curable group in the body (B,) is a methacryloxy group having a low reactivity.

非硬化性寡聚物(D)的分子量=56 1xBx1〇〇〇/a ...(1) 就硬化後的樹脂層彈性模數容易變為更低的觀點，非 硬化性寡聚物(D)較佳係使用聚氧伸烷基多元醇、更佳係使 用聚氧伸丙基多元醇。又，如後述，為調節非硬化性募聚 物(D)的極性，亦可將聚氧伸丙基多元醇的氧伸丙基一部分 利用氧伸乙基進行取代。亦可將氧伸丙基一部分利用氧伸 乙基進行取代，此部分係與前述多元醇⑴中的說明相同。 例如就相溶性的觀點，較佳為寡聚物(A，)係將聚氧伸烷 基多元醇與聚異氰酸酯使用為原料而合成的胺甲酸酯募聚 物，而非硬化性寡聚物(D)係聚氧伸烷基多元醇。 本發明中’為使未硬化時的樹脂層形成用光硬化性樹 脂組成物呈安定，俾抑制非硬化性寡聚物(D)從硬化後的樹 脂層中分離，較佳係寡聚物(Αι)與非硬化性寡聚物(D)具有 相同結構或類似結構的分子鍵。 具體而言’在合成樹脂層形成用光硬化性樹脂組成物 中之寡聚物(A1)時的原料，較佳係使用例如多元醇等具羥基 的化合物（以下亦稱「含羥基化合物」），且將該相同的含羥 基化合物使用為非硬化性寡聚物(D)。 例如當养聚物(A')係將聚氧伸烷基多元醇與聚異氰酸 酯使用為原料而合成的胺曱酸酯寡聚物時，較佳係將該聚 38 201206701 氧伸院基多元醇使用作為非硬化性S聚物(D)。 或者，當使用為寡聚物(A，)原料的含羥基化合物、與使

例如秦聚物(A’)係使用了氧伸丙基一部分利用氧伸乙 基進行取代的聚氧伸丙基多元醇⑻、及聚異氰賤酷，作為 原料而合成的胺旨募聚物時，作為非硬化性暮聚物⑼ 杈佳係使用不具有氧伸乙基的聚氧伸丙基多元醇，且平均1 個經基的分子量小於前述多元醇⑻的聚氧伸兩元醇 者。 最佳的樹脂層形成用光硬化性樹脂組成物〜例，係有 如下述寡聚物(A')、非硬化性寡聚物(D)、及單體(仏)的組成 物’該寡聚物(Α’)係使氧伸丙基一部分已利用氧伸乙基進行 取代的聚氡伸丙基二醇、與聚異氰酸酯化合物進行反應而 獲得具有異氰酸酯基的預聚物之後，與前述單體(Β2)進行 反應而獲得之胺曱酸酯募聚物(Α2);該非硬化性募聚物(D) 係與該胺曱酸酯寡聚物(八2)的原料相同，將氧伸丙基一部 分已利用氧伸乙基進行取代的聚氧伸丙基二醇；且，該單 體(Β’)係具有羥基的單體(Β3)。 39 201206701 依此，若寡聚物(A')部分性具有與非硬化性寡聚物(D) 相同的分子結構，便可更加提高組成物中的非硬化性寡聚 物(D)之相溶性’更藉由單體(B1)具有羥基，判斷利用硬化 性化合物(II)硬化後的分子結構中之經基、與非硬化性寡聚 物(D)的分子結構中之羥基間的相互作用，便可使非硬化性 寡聚物(D)安定地存在於硬化物中。 再者’其他例方面’含有下述寡聚物(A')、非硬化性寡

固疋支撐盤上’依硬化性樹脂組成物之面朝上的方式，平 放第1面材。 在減壓裝置内的上部，設有可朝上下方向移動的移動 支撐機構，在移動支撐機構上安裝有第2面材。當第2面材 係顯示元件的情況，便將顯示影像該側的表面朝下。當在 第2面材的表面設有抗反射層之情況，便將沒有形成抗反射 層之側的表面朝下。 第2面材係放置於第1面材的上方，且不與樹脂層形成 用光硬化性樹脂組成物接觸的位置處。即，使第1面材上的 樹脂層形成用光硬化性樹脂組成物、與第2面材不會相接觸 地呈相對向。 201206701 另外亦可將可於上τ方向移㈣移動讀機構設置 於減屡裝置㈣下部，並在移動支職構之上放置已被供 應硬化_旨組絲州面m第爾係安裝 於在減壓裝置内的上部所設置之固定支擇盤上，並使第1面 材與第2面材呈相對向。 亦可將第1面材與第2面材 裝置内的上下之移動支撐機構所支撐- 年第1面材與第2面材配置於既定位置後，便對減壓裝 置的内部施行減壓而形成既定的減壓環境。若可能的話， 亦可在減壓操作巾、或經形錢定紐環境之後，便在滴 壓裝置内㈣1面材與第2面材位於既定位置處。 在減壓裝置的内部成為減壓環境之後，便將由彩 :支:機構所支撐的第2面材朝下方移動,俾使第2面㈣ 於+1面材上的樹脂層形成用光硬化性樹脂組成物之上 =使進行重疊’便在由^面材的表面（以顯示元卡 m影像顯示之側的表面）、第2面材的表面（以顯示； 空間^Ϊ影像顯示之側的表面）、及未硬化密封部戶㈣ 二备、密封著樹脂磨形成用光硬化性樹脂組成物。 田進订重疊之際，利用第2面材的自重 =Γ，使樹脂層形成__二= 址成物，2前述空間内充滿樹脂層形成用光硬化性糾 氣泡少或Γ在步驟⑷中暴露於高壓力環境時，便形』 層。&lt;魏泡的樹麟形成用光硬化,_脂組成物 42 201206701 進行重疊時的減壓環境係l〇〇pa以下、較佳係1〇?3以 上。若減壓環境屬於太過低壓，便會有對樹脂層形成用光 硬化性樹脂組成物中所含各成分(諸如硬化性化合物、光聚 合起始劑、聚合終止劑、光安定劑等）造成不良影響的可能 性。例如若減壓環境屬於太過低壓，則各成分便會有氣化 的可忐性，且為提供減壓環境會耗費時間。減壓環境的壓 力較佳係15〜40Pa。 從使第1面材與第2面材相重疊的時點起迄解除減壓環 境為止的時間並無特別的限定，可在樹脂層形成用光硬化 性樹脂組成物密封後，便馬上解除減壓環境，亦可在樹脂 層形成用光硬化性樹脂組成物密封後，將減壓狀態維持既 定時間。藉由將減壓狀態維持既定時間，樹脂層形成用光 硬化性樹脂組成物便在密閉空間内流動，而使第丨面材與第 2面材間的間隔呈均勻’即便提高環賴力仍可輕易地維持 密封狀態。維持減壓狀態的時間係可為數小時以上的長時 間，就生產效率的觀點，較佳係！小時以内、 ’ d 佳係10分鐘 的密封部形 的情况，可 用光硬化性 本實施形態的製造方法中，當塗佈黏度高 成用光硬化性樹脂組成物而形成未硬化密封部 將由步驟(c)所獲得之層積前驅體的樹脂層形成 树月曰組成物厚度設為10 μηι〜3 mm的較厚狀態。 [步驟(d)] 月1J驅體玫 在步驟(c)中，經解除減壓環境後，便將層積 置於環境壓力達50kPa以上的壓力環境下。 43 201206701 右將層積刖驅體放置於50kPa以上的麼力環境下，第1 面材與第2面材便利用上升的壓力朝相密接的方向被按 押，因而若在層積前驅體内的密閉空間中有存在氣泡，樹 脂層形成用光硬化性樹脂組成物會流動於氣泡中，便使密 閉空間整體由樹脂層形成用光硬化性樹脂組成物均勻地填 充。 壓力環境通常係80kPa〜120kPa。壓力環境係可為大氣 壓環境、亦可為高於此的壓力。就樹脂層形成用光硬化性 樹脂組成物的硬化等操作可在不需要特別設備情況下實施 的觀點，較佳為大氣壓環境。 從將層積前驅體放置於5 〇kPa以上的壓力環境下之時 點起、迄樹脂層形成用光硬化性樹脂組成物開始硬化為止 的時間（以下稱「高壓保持時間」）並無特別的限定。當將層 積前驅體從減壓裝置中取出並移動至硬化裝置，直到開始 硬化為止的製程均在大氣壓環境下進行的情況，此項製程 所需要的時間便成為向壓保持時間。所以，當在放置於大 軋屋環化下的時點，於層積前驅體的密閉空間内已無存在 氣泡的情況，或者在該製程期間内氣泡消失的情況，均可 馬上使樹脂層形成用光硬化性樹脂組成物硬化。當直到氣 泡消失為止須耗時間的情況，便在截至氣泡消失為止前， 均將層積前驅體保持於5〇kPa以上的壓力環境下。又，因為 即便高壓保持時間延長’通常仍不會構成阻礙，因而就製 程上的其他必要性，亦可延長高壓保持時間。高壓保持時 間係可為1日以上的長時間，但就生產效率的觀點較佳係 44 201206701 6小時以内、更佳係1小時以内，就提高生產效率的觀點， 特佳在10分鐘以内。 接著，以將層積前驅體放置於50kPa以上的壓力環境下 之狀態，藉由使樹脂層形成用光硬化性樹脂組成物進行硬 化，便形成可將顯示元件與保護板予以接合的樹脂層，可 製得顯示裝置。 樹脂層形成用光硬化性樹脂組成物及密封部形成用光 硬化性樹脂組成物，係照射光而使硬化。例如從光源（諸如 紫外線燈、高壓水銀燈、黑燈、化學燈、UV-LED等）照射 紫外線或短波長可見光，而使光硬化性樹脂組成物硬化。 再者’此時，由密封部形成用光硬化性樹脂組成物所 形成的未硬化密封部，係可與樹脂層形成用光硬化性樹脂 組成物的硬化同時進行硬化，亦可在樹脂層形成用光硬化 性樹脂組成物進行硬化前便使預先硬化。又，當透明面材 其中一部分有形成遮光印刷部，並由遮光印刷部挾持而形 成密封部的情況，因為在樹脂層形成用光硬化性樹脂組成 物的硬化時所採取之利用通過透明面材之透光部的光使密 封部硬化係有困難，因而亦可在樹脂層形成用光硬化性樹 脂組成物硬化之後才使密封部硬化。 例如從層積前驅體的第丨面材及第2面材中具有光穿透 性之側，對樹脂層形成用光硬化性樹脂組成物施行光照 射，且從層積前驅體側邊，對由遮光部及顯示元件所包夾 的未硬化抖部及職相制光魏性難料物，施 行光照射。 &amp; 45 201206701 ^第1面材及第2面材當中’因為顯示元件在未啟動的狀 “、下並不具有光穿透性，因而從成為保護板的透明面材之 側通過透光部施行光照射。 再者，若在透明面材的周邊部設置遮光印刷部，並在 由遮光印顯與齡元件所挾制_巾有存在未硬化密 封部或樹脂層形成用光硬化性樹脂組成物，則僅依靠來自 透明面材之透光㈣光並餘充分硬化。所以，從顯示元 件的側邊施行光照射。 光較佳係紫外線、或450nm以下的可見光。特別係當在 透明面材上設有抗反射層，且抗反射層或已形成抗反射層 的，明樹脂薄膜、或者在該抗反射_與透明面材間設有 黏著層等紫外線無法穿透的情況，便必須可見光進行 硬化。 從側邊進行光照射的光源，係可使用當採取從透明面 材側進行光照射時所使用的麵，但就光源的配置空間、 與適用於特定地方的有效率光照射之觀點，較佳係使用紫 外線、或發出45Gnm以下之可見光的LED。 光…、射的步驟係可在從透明面材一側施行光照射之後 ^從側邊施行光照射，亦可相反，或同時施行光照射，為 能更純進遮光印卿的未硬化密封部與樹闕形成用光 樹月g組成物的光硬化，較佳係先從側邊施行光照 :、或與側邊同時從透明面材側施行光照射…當經光 .，、、射後4會騎脑層形成用光硬化性㈣喊物的硬 夺或者光硬化性樹脂組成物的硬化需要時間等 46 201206701 情況時，亦可在樹脂層形成衫硬域樹料·的硬化 大致完成後，再湘從側邊的光照射而使密封部硬化。 [具體例] 本實施形態的製造方法中，第丨面#係可任意使 材、或使用表面材。糾，顯示裝置係配合第丨面材的選擇， 可分別依照以下2種方法進行製造。 (α-l)第1面材係使用顯示元件（背面材），第2面材係使 用成為保護板的透明面材（表面材）之方法。 ㈣第！面材係使用成為保護板的透明面材（表面 材），第2面材係使用顯示元件（背面材）的方法。 以下，以方法(cx-D的情況為例，針對第i圖的顯示裝置 之製造方法’使用圖式進行具體說明。 (步驟(a)) 如第3圖與第4圖所示’沿顯示元件5〇(&amp;面材）的周緣 部’利用分配機(未圖示）等塗佈密封部形成用光硬化性樹脂 組成物，而形成未硬化密封部丨2。 在顯示元件的外周部設置有傳遞用以使顯示元件啟動 電乳信號的FPC等線構件。本實施形態的製造方法中， 當保持各面㈣，就使配線構件軸置較為容易之觀點， 最好將顯示元件當作第1面材並配置於下側。 ··· (步驟(bX) 接著，如第5®及第6圖所*，對由顯示元件5Q的未硬 化密封部12所包圍矩形狀區域13供應樹脂層形成用光硬化 性樹㈣成物14。樹脂層形成用光硬化性樹餘成物叫 47 201206701 供應量係預先設定為由未硬化密封部12與顯示元件5〇及透 明面材10(參照第7圖）所密閉的空間，剛好能利用樹脂層形 成用光硬化性樹脂組成物14填滿的量。 樹脂層形成用光硬化性樹脂組成物14的供應係如第5 圖及第6圖所示，將顯示元件50平放於下定盤18上，利用在 水平方向移動的分配機20，呈線狀、帶狀或點狀供應樹脂 層形成用光硬化性樹脂組成物14而實施。 分配機20係利用由一對導螺22、及與導螺22呈正交的 導螺24所構成之公知水平移動機構，可在區域13的全範圍 中進行水平移動。另外，亦可取代分配機2〇，改為使用模 具塗佈機。 (步驟(c)) 接著’如第7圖所示’將顯示元件5〇與透明面材1〇(第2 面材)搬入減壓裝置26内。在減壓裝置26内的上部，配置有 具備複數吸附墊32的上定盤30，並在下部設置有下定盤 31 °上定盤30係利用氣缸34可於上下方向移動。 透明面材10係安裝於吸附墊32上。顯示元件50係將被 供應樹脂層形成用光硬化性樹脂組成物14之面朝上，固定 於下定盤31之上。 接著’利用真空泵28抽吸減壓裝置26内的空氣。減壓 裝置26内的環境壓力係在到達例如15〜40Pa減壓環境之 後’便在將透明面材1〇利用上定盤3〇的吸附墊32進行吸附 保持的狀態下，朝向下方呈待機的顯示元件50 ’使氣缸34 啟動而下降。然後，使顯示元件50與透明面材1〇隔著未硬 48 201206701 化密封部12相重疊，而構成層積前驅體，並在減壓環境下 保持層積前驅體既定時間。 另外，顯示元件50對下定盤31的安裝位置、吸附墊32 的個數、以及透明面材10對上定盤30的安裝位置等，係配 合顯示元件50及透明面材10的尺寸、形狀等而適當調整。 此時，吸附墊係使用靜電吸盤，藉由採用日本特願 2008-206124所附說明書（納入本說明書中）所記載的靜電吸 盤保持方法，可將玻璃基板安定地保持於減壓環境下。 (步驟(d)) 接著，將減壓裝置26的内部形成例如大氣壓之後，便 從減壓裝置26取出層積前驅體。若將層積前驅體放置於大 氣壓環境下，層積前驅體之顯示元件50側的表面與透明面 材10側的表面便利用大氣壓而被按押，而密閉空間内的樹 脂層形成用光硬化性樹脂組成物14則被顯示元件5 0與透明 面材10加壓。利用該壓力，密閉空間内的樹脂層形成用光 硬化性樹脂組成物14會流動，密閉空間整體便由樹脂層形 成用光硬化性樹脂組成物14均勻地填充。 接著，在透明面材上設置遮光印刷部，當使由遮光印 刷部所挾持的未硬化密封部與樹脂層形成用光硬化性樹脂 組成物先行硬化時，便如第8圖所示，從層積前驅體的側 邊，對由遮光印刷部55及顯示元件50所包夾的未硬化密封 部12及樹脂層形成用光硬化性樹脂組成物14，涵蓋顯示元 件全周施行光（紫外線、或450nm以下的可見光）照射，且從 透明面材10之側，透過透光部56對樹脂層形成用光硬化性 49 201206701 樹脂組成物η施行光（紫外線、或物⑽以下的可見光）照 射，而使層積__㈣未硬化密封部12及樹脂層形成 用光硬化性樹脂組成物14進行硬化，便製得顯示裝置i。 曰透明面材上無设置遮光印刷部的情況，便從透明面 材ίο之側涵蓋層積前驅體全面施行光照射，藉由使層積前 驅體内部的未硬化㈣和及樹脂層形成用光硬化性樹脂 組成物14進行硬化，便製得顯示裝置j。 以上，就方法(α-l)的情況為例，針對本實施形態的顯 示裝置之f造方法進行具體制，而其他方法(α·2)的情況 亦同樣的可製造顯示裝置。 [作用效果：顯示裝置之製造方法] 根據以上所說明本實施形態的顯示裝置之製造方法， 可在樹脂層中不會產生氣泡的情況下，製造大面積的顯示 裝置。假設即便在減壓下已密封的樹脂層形成用光硬化性 樹脂組成物中有氣泡殘存’對硬化前在高壓力環境下已密 封的樹脂層形成用光硬化性樹脂組成物施加該壓力，便可 減少該氣泡的體積，俾使氣泡容易消失。例如在l〇〇Pa下已 密封的樹脂層形成用光硬化性樹脂組成物中，氣泡中的氣 體體積可認為係在100kPa下的1/1000。因為氣體亦會溶解 於樹脂層形成用光硬化性樹脂組成物中，因而微小體積氣 泡中的氣體會迅速溶解於樹脂層形成用光硬化性樹脂組成 物中並消失。 再者，因為即便對密封後的樹脂層形成用光硬化性樹 脂組成物施加大氣壓等壓力’液狀樹脂層形成用光硬化性 50 201206701 樹脂組成物域於流動性的組成物，因而該壓力係均句分 佈在顯不几件的表面上’不會對接觸到樹脂層形成用光硬 化性樹脂組成物的顯示元件表面—部分施加在此以上的應 力，對顯示元件造成損傷的威脅低。 再者由树月曰層形成用光硬化性樹脂組成物的硬化所 形成之则日層、與顯不元件、透明面材間之界面接著力， 高於利用紐制錢的界面接著力。且，對流動性樹脂 層形成絲硬化性如旨③成物加壓而密接於顯示元件、透 明面材的表面上’並使在此狀態下硬化，因而可獲得更高 的界面接著力’且可獲得對顯示元件、透明面材的表面呈 均勻的接著’界面接著力局部性降低的情況很少。

Further, when the monomer (B3) is contained, good adhesion between the face material and the resin layer can be obtained lightly (4). The number of hydroxyl groups in the oxime molecule of the monomer (1)" can be arbitrarily selected so that the non-curable oligomer (D) can be stabilized. However, from the viewpoint of easiness, it is preferable to have 丨 in one molecule. The monomer (B3) having a hydroxyl group is, for example, the same as the monomer (B3) in the photocurable resin composition for forming a sealing portion, and preferably 2-hydroxybutyl methacrylate. The content ratio of the monomer (B3) is in the total (1% by mass) of the curable compound (11), that is, the total (1% by mass) of the polymer (A') and the monomer (B). It is preferably 10 to 60% by mass, and more preferably 20 to 50% by mass. When the content of the monomer (B3) is 10% by mass or more, the photocurable resin composition for forming a resin layer can be easily obtained sufficiently. When the content of the monomer (B3) is 6 〇 mass% or less, the cured product of the resin layer forming photocurable resin composition is cured by the effect of improving the stability of the resin and the adhesion between the surface material and the resin layer. The hardness does not become too high, and thus is preferable. The monomer (B') is preferably contained in terms of mechanical properties of the resin layer. The monomer (B4) is because the monomer (B4) lowers the glass transition temperature (Tg) of the resin layer after hardening, thereby contributing to a decrease in the elastic modulus of the resin layer after hardening, and the resin layer can be lifted. However, when the curability of the photocurable resin composition for forming a resin layer is formed and the time required for curing is shortened, it is preferable to reduce the content of the monomer (B4) or not. The monomer (B4): one or more selected from the group consisting of alkyl methacrylates having an alkyl group having 8 to 22 carbon atoms. When the carbon number is 8 or more, the hard 34 201206701 compound can be obtained. The viewpoint of lowering the glass transition temperature is preferable, and if the carbon number is 22 or less, it is preferable from the viewpoint that the alcohol of the raw material can be easily obtained by a natural substance. The monomer (B4) is, for example, a methyl group. N-dodecyl acrylate decyl decyl acrylate, decyl ruthenium phthalate, etc., preferably n-dodecyl methacrylate or n-octadecyl methacrylate The content of the monomer (B4) is in the entire curable compound (η) (1% by mass) That is, in the total (100% by mass) of the oligomer (A') and the monomer (B), it is preferably 5 to 50% by mass, more preferably 15 to 40% by mass. If the monomer (B4) is used When the content ratio is 5% by mass or more, the sufficient addition effect of the monomer (B4) can be easily obtained. (Photopolymerization initiator (C2)) Photopolymerization contained in the photocurable resin composition for resin layer formation Examples of the starting agent (C2) include acetophenone-based, ketal-based, benzoin or benzoin ether, phosphine oxide-based diphenylketone, thioxanthone, and fluorene-based light. The polymerization initiator is preferably a phosphine oxide-based or an oxonone-based photopolymerization initiator, and is preferably a phosphine oxide-based one from the viewpoint of suppressing coloration after photopolymerization. The content of the photopolymerization initiator (C2) of the photocurable resin composition for forming a resin layer is the total of the curable compound (11), that is, the total of the oligomer 仏, and the monomer (B') 丨00 The mass part is preferably 〇〇1 to 1 part by mass, more preferably 0. 1 to 5 parts by mass. When a part of the photocurable resin composition for forming a resin layer adjacent to the sealing material is hardened by the light irradiated from the side of the surface material, the photopolymerization unit preferably has a composition (C 2 ). The absorption wavelength region (λ2) exists on the longer wavelength side than the absorption wavelength region (λΐ) of the photopolymerization initiator (C1). Photopolymerization The initiator (C2) may have an absorption wavelength region (λ2) or an absorption wavelength region (λΓ) and an absorption wavelength region (λ2) which are repeated with the absorption wavelength region (λΐ). (Non-curing oligomer (D)) The non-curable oligomer (D) is excellent in compatibility with the photocurable resin composition for forming a resin layer and does not contribute to hardening, so that it can be prevented from being damaged. In the case of transparency and homogeneity, stress generated by shrinkage at the time of hardening of the resin layer is reduced. When the non-curable oligomer (D) is cured by the photocurable resin composition for forming a resin layer, it does not undergo a curing reaction with the curable compound (π) in the composition, and has a 〇8~ per molecule. 3 hydroxyl oligomers. Preferably, the number of hydroxyl groups per molecule is 2 to 3. If the hydroxyl group per molecule reaches 8 or more ' between the non-hardening oligomers, or between the non-hardening polymer and the hardened material obtained from the hardening compound (II), the interaction between the two In view of the fact that the non-curable oligomer is stably maintained, the non-curable oligomer can be formed into a photocurable resin composition for forming a resin layer. The viewpoint of compatibility is preferred. The number average molecular weight () of the non-hardening oligomer (D) on the average of j warp groups is preferably ir, 4 〇〇 8 8 _. If the average number of molecular weights of the average of one warp group is up, the polarity of the non-hardenable ♦polymer (D) does not become too high, and the hardening property of the (4) _ Guang Wei, _ test towel can be easily obtained. Good compatibility between the two). If the average number of i warp groups is 36 201206701 below 8000', the interaction between the hydroxyl group derived from the curable compound (II) and the hydroxyl group of the ruthenium (D) can be easily obtained. In the latter lipid layer, the non-sclerosing oligomer (9) is stabilized. The interaction of the Hi-term interaction is estimated to be due to hydrogen bonding. The non-curable oligomer (D) may be used singly or in combination of two or more. Examples of the ^ 3 &amp; base non-hardening oligomer (D) include, for example, oxime alcohol in a polymer, preferably a polyoxyalkylene-based polyol '«polyol, polycarbonate polyol . The polyoxyalkylene-based polyol may, for example, be a polyoxyalkylene monool 'polyoxyalkylene diol or a polyoxyalkylene triol having a carbon number of 2 to 4 by oxygen stretching: a repeating unit. Specifically, for example, polyoxyethylene glycol, polyoxylated propylene alcohol ('Ig propylene glycol'), polyoxypropylene glycerol, polyoxytetradecyl diol, and the like can be given. The average molecular weight of the polyoxyalkylene-based polyol average (four) radicals _' is preferably _~ coffee, better _~5_. The polyhydric polyol may, for example, have an aliphatic diol residue such as ethylene glycol, propylene glycol or 1,4·butylene glycol, and an aliphatic such as glutaric acid, adipic acid or sebacic acid. An aliphatic polyglycol diol having a dicarboxylic acid residue. Examples of the polycarbonated polyhydric alcohols include aliphatic polymers such as ruthenium residues having a diol residue such as 1,6-hexanediol, and aliphatic groups such as a ring-opening polymer of an aliphatic carbonaceous Polycarbonate diol. The average amount of the poly-S-70 or the polycarbonate polyol is averaging in the knife (Μη), preferably 400~8〇〇〇, and more preferably the system~働〇. 37 201206701 In the present specification, the number average molecular weight of the non-curable oligomer (D) is a hydroxyl value a (k〇h mg/g)' and non-hardening oligomerization measured according to JIS K1557-1 (2007 edition). The number (1) of the hydroxyl group B in one molecule is a value calculated according to the following formula (1). Molecular weight of the non-curable oligomer (D) = 56 1xBx1 〇〇〇 / a (1) The non-curable oligomer (D) is easy to change from the viewpoint that the elastic modulus of the resin layer after hardening is lower. Preferably, a polyoxyalkylene polyol is used, and more preferably a polyoxypropylene propylene polyol is used. Further, as described later, in order to adjust the polarity of the non-curable polymer (D), a part of the oxygen-extended propyl group of the polyoxy-extension propylene polyol may be substituted with an oxygen-extended ethyl group. Further, a part of the oxygen-extended propyl group may be substituted with an oxygen-extended ethyl group, which is the same as described in the above polyol (1). For example, from the viewpoint of compatibility, it is preferred that the oligomer (A,) is a carbamate condensate synthesized by using a polyoxyalkylene polyol and a polyisocyanate as a raw material, instead of a curable oligomer. (D) is a polyoxyalkylene polyol. In the present invention, the photocurable resin composition for forming a resin layer when uncured is stabilized, and the non-curable oligomer (D) is inhibited from being separated from the cured resin layer, preferably an oligomer ( Αι) A molecular bond having the same structure or a similar structure as the non-hardening oligomer (D). Specifically, it is preferable to use a compound having a hydroxyl group such as a polyhydric alcohol (hereinafter also referred to as "hydroxyl-containing compound") as a raw material in the case of forming the oligomer (A1) in the photocurable resin composition for a synthetic resin layer. And the same hydroxyl group-containing compound is used as the non-hardening oligomer (D). For example, when the aramid (A') is an amine phthalate oligomer synthesized by using a polyoxyalkylene polyol and a polyisocyanate as a raw material, it is preferred to use the poly(201206001) oxygen-based polyol. Used as a non-hardening S polymer (D). Alternatively, when a hydroxyl group-containing compound which is a raw material of the oligomer (A) is used, and a ruthenium-containing compound which is used as the non-hardened county (4) (9), it is not the same thing. It is preferable that the molecular chain has a common repeating unit or the like. And there are 4 接 接 、 、 /, /, 、,. And set the polarity of the two to the same extent. The adjustment of the polarity is, for example, a method of increasing the polarity by introducing a polar group, a method of increasing the salicyl property by substituting a propyl-partial portion with an oxygen-extended ethyl group, and a molecular weight of decreasing the average Η-based group. And the method of increasing the polarity, etc. Methods such as shai can also be used in combination. For example, the Qin polymer (A') is an amine-polymerized polymer synthesized by using a polyoxy-extension propylene polyol (8) in which an oxygen-extended propyl group is substituted with an oxygen-extended ethyl group, and a polyisocyanuric acid. When the non-curable ruthenium polymer (9) is used as a polyoxy-extension propylene polyol having no oxygen-extended ethyl group, and the average molecular weight of one of the radicals is less than that of the polyhydric alcohol (8) . The photocurable resin composition for forming an optimum resin layer is exemplified by the following composition of oligomer (A'), non-curable oligomer (D), and monomer (仏). The polymer (Α') is obtained by reacting a part of an oxygen-extended propyl group with a poly(propylidene glycol) substituted with an oxygen-extended ethyl group, and reacting with a polyisocyanate compound to obtain a prepolymer having an isocyanate group, The amine phthalate condensate (Α2) obtained by the reaction of the body (Β2); the non-hardening polymer (D) is the same as the raw material of the amine phthalate oligomer (VIII), and the oxygen is extended. A polyoxypropyl propylene glycol in which a part of the propyl group has been substituted with an oxygen-extended ethyl group; and the monomer (Β') is a monomer having a hydroxyl group (Β3). 39 201206701 Accordingly, if the oligomer (A') partially has the same molecular structure as the non-curable oligomer (D), the phase of the non-hardening oligomer (D) in the composition can be further enhanced. Further, the solubility of the monomer (B1) has a hydroxyl group, and it is judged that the radical group in the molecular structure after hardening of the curable compound (II) and the hydroxyl group in the molecular structure of the non-hardenable oligomer (D) The non-hardening oligomer (D) can be stably present in the hardened body. Further, the 'other aspect' includes a composition of the following oligomer (A'), non-curable oligomer (D), and monomer (B'), and a non-hardening oligo in the composition can also be obtained. The polymer (D) is in good compatibility, and the non-hardening oligomer (D) can be stably present in the cured product. The oligomer (A') is obtained by reacting a polyoxypropyl propylene glycol partially substituted with an oxygen-extended ethyl group with an oxygen-extended ethyl group to obtain a pre-isocyanate group. After the polymer, an amine phthalate oligomer (A2) obtained by reacting with the aforementioned monomer (B2), the non-hardening oligomer (D) is a polyoxygen-extended polypropylene which is not substituted with an oxygen-extended ethyl group. a polyglycol propylene glycol having a molecular weight smaller than that of the amine phthalate oligomer (A2) raw material; and the monomer (Β1) is a monomer (B3) having a hydroxyl group. The content of the non-curable oligomer (D) in the photocurable resin composition for forming a resin layer is preferably from 1 to 90% by mass. When the content of the non-curable oligomer is 10% by mass or more, the effect of lowering the stress generated by the shrinkage of the resin during curing can be easily obtained. If the quality is less than 9 ❶ / ,, the face materials can be easily fixed to each other, and the time-dependent positional displacement of the surface material and the back material can be easily and satisfactorily prevented. The content of the non-curable oligomer (D) is preferably such a ratio as to match the composition of the curable compound (π), and is set to a state in which a storage shear modulus and a loss tangent are preferably obtained. A more preferable range is 30 to 80% by mass. (Additive) The photocurable resin composition for forming a resin layer may contain, for example, a polymerization terminator, a photohardening accelerator, a chain transfer agent, a light stabilizer (such as an ultraviolet absorber, a radical scavenger, etc.). Various additives such as an antioxidant, a flame retardant W, an adhesion enhancer (such as a sulphur coupler), a pigment, a dye, and the like preferably contain a polymerization terminator or a light stabilizer. In particular, it is possible to modify the stability of the photocurable resin composition for forming the base resin layer by adjusting the polymerization terminator which is less than the amount of the t-starting agent, and to adjust the molecular weight of the cured resin layer. [Step (C)] After the step (b), the first surface material to which the photocurable tree-forming composition for resin layer formation is supplied is placed in a decompression device and fixed in a decompression device. On the support disk, the first face material is placed flat with the surface of the curable resin composition facing up. A moving support mechanism that can move in the vertical direction is provided in an upper portion of the decompression device, and a second surface material is attached to the movable support mechanism. When the second face material is the display element, the surface on the side where the image is displayed faces downward. When the antireflection layer is provided on the surface of the second face material, the surface on the side where the antireflection layer is not formed faces downward. The second face material is placed above the first face material and is not in contact with the photocurable resin composition for forming the resin layer. In other words, the photocurable resin composition for forming a resin layer on the first surface material is opposed to the second surface material without coming into contact with each other. 201206701 In addition, the movable reading mechanism that can be moved in the upper τ direction (4) can be placed in the lower part of the reducing device (4), and placed on the mobile support structure has been supplied with hardening _ the group of silk state m dynasty installed in the reduction The fixed portion provided in the upper portion of the pressing device is fixed to the disc, and the first surface material and the second surface material are opposed to each other. The first surface material and the second surface material in the second surface material device can be supported by the vertical movement support mechanism. When the first surface material and the second surface material are placed at a predetermined position, the inside of the pressure reduction device can be decompressed. Form a defined decompression environment. If possible, after the decompression operation towel or the shape of the money setting, the inside of the drip device (4) 1 face material and the second face material are located at a predetermined position. After the inside of the decompression device is in a reduced pressure environment, the second surface material supported by the mechanism is moved downward, and the second surface (four) is cured on the +1 surface material. Above the resin composition = the overlap is made on the surface of the surface material (the surface on the side where the meta-card m image is displayed), and the surface of the second surface material (in the display; the space is displayed on the side of the image) (Surface) and uncured seal parts (4) Two parts, sealed with a photocurable resin composition for resin grinding. When the field is overlapped, the self-weight of the second face material = Γ, the resin layer is formed into a __ two = address product, and the space in which the resin layer is filled is less light-curable or less in the step (4). When exposed to high pressure environments, the layer is shaped. &lt;The formation of the vesicles of the vesicles is cured by light, and the _ lipid composition 42 201206701 The pressure reduction environment at the time of superposition is l〇〇pa or less, preferably 1 〇 3 or more. If the reduced pressure environment is too low pressure, the components contained in the photocurable resin composition for forming a resin layer (such as a curable compound, a photopolymerization initiator, a polymerization terminator, a light stabilizer, etc.) may be caused. The possibility of adverse effects. For example, if the decompression environment is too low pressure, the components will be vaporizable and it will take time to provide a reduced pressure environment. The pressure in the reduced pressure environment is preferably 15 to 40 Pa. The time from the time when the first surface material and the second surface material are overlapped with each other is not particularly limited, and the resin layer forming photocurable resin composition can be sealed immediately after being sealed. In the environment, after the resin layer forming photocurable resin composition is sealed, the reduced pressure state can be maintained for a predetermined period of time. By maintaining the reduced pressure state for a predetermined period of time, the photocurable resin composition for forming a resin layer flows in the sealed space, and the interval between the second surface material and the second surface material is made uniform even if the looping force is increased. The sealing state can be easily maintained. The time for maintaining the decompressed state can be a long time of several hours or more, and it is preferable from the viewpoint of production efficiency! In the case of the sealing portion of the "10" for 10 minutes, it is possible to use photocurability. In the production method of the present embodiment, when the viscosity is high, the photocurable resin composition is formed to form an uncured seal portion. c) The resin layer of the obtained laminated precursor forms a thicker state in which the thickness of the dendritic composition is set to 10 μηι to 3 mm. [Step (d)] Month 1J body rose In step (c), after the decompression environment is released, the layer is placed under a pressure environment having an ambient pressure of 50 kPa or more. 43 201206701 The right side of the laminated sputum body is placed in a force environment of 50 kPa or more, and the first surface material and the second surface material are conveniently pressed in the direction of close contact with the rising pressure, so if the laminated body is in the laminated body In the sealed space, air bubbles are present, and the resin layer-forming photocurable resin composition flows into the cells, so that the entire sealed space is uniformly filled with the resin layer-forming photocurable resin composition. The pressure environment is usually 80 kPa to 120 kPa. The pressure environment can be an atmospheric pressure environment or a pressure higher than this. The operation of hardening or the like of the photocurable resin composition for forming a resin layer can be carried out without requiring special equipment, and is preferably an atmospheric pressure environment. The time from when the laminated precursor is placed in a pressure environment of 5 kPa or more, and the time until the resin layer forming photocurable resin composition starts to harden (hereinafter referred to as "high pressure holding time") is not particularly limited. . When the laminated precursor is taken out from the decompression device and moved to the hardening device until the process of starting hardening is performed under an atmospheric pressure environment, the time required for the process becomes the forward pressure holding time. Therefore, when it is placed under the circling of the large rolling house, there is no bubble in the sealed space of the laminated precursor, or the bubble disappears during the process, and the resin layer can be formed immediately. The photocurable resin composition is hardened. When it takes time until the bubble disappears, the laminated precursor is maintained in a pressure environment of 5 kPa or more until the bubble disappears. Moreover, since even if the high-voltage holding time is extended, "there is usually no hindrance, and the high-pressure holding time can be prolonged in terms of other necessity in the process. The high-pressure holding time may be a long time of one day or more, but from the viewpoint of production efficiency, it is preferably within 4 hours, more preferably within 1 hour, and more preferably within 1 hour, and the viewpoint of improving production efficiency is particularly preferably within 10 minutes. Then, by placing the laminated precursor in a pressure environment of 50 kPa or more, the resin layer forming photocurable resin composition is cured to form a resin layer capable of bonding the display element and the protective sheet. A display device can be produced. The photocurable resin composition for forming a resin layer and the photocurable resin composition for forming a sealing portion are cured by irradiation with light. For example, a light source (such as an ultraviolet lamp, a high pressure mercury lamp, a black lamp, a chemical lamp, a UV-LED, or the like) is irradiated with ultraviolet rays or short-wavelength visible light to harden the photocurable resin composition. In this case, the uncured seal portion formed of the photocurable resin composition formed of the seal portion can be cured simultaneously with the curing of the photocurable resin composition for forming the resin layer, or can be formed in the resin layer. The hardening resin composition is pre-hardened before being hardened. In addition, when a part of the transparent surface material is formed with a light-shielding printing portion and is held by the light-shielding printing portion to form a sealing portion, the use of the transparent surface material is performed when the resin layer forming photocurable resin composition is cured. Since the light in the light transmitting portion is difficult to harden the sealing portion, the sealing portion can be cured only after the resin layer forming photocurable resin composition is cured. For example, the light-curable resin composition for forming a resin layer is irradiated with light from the side surface of the second surface material of the laminated precursor and the second surface material, and the side of the laminated precursor is aligned. The light is irradiated by the unhardened shaker portion and the light-repellent material which are sandwiched between the light-shielding portion and the display element. &amp; 45 201206701 ^In the first face material and the second face material, 'because the display element is in an unactuated shape, and there is no light penetration underneath, the light transmissive portion passes through the side of the transparent face material that serves as the protective plate. In addition, a light-shielding printing portion is provided in the peripheral portion of the transparent surface material, and the opaque sealing portion or the photo-curable resin composition for forming a resin layer is formed by the light-shielding printing and ageing element. However, it relies only on the light-transmitting (four) light from the transparent surface material and is sufficiently hardened. Therefore, light irradiation is performed from the side of the display element. The light is preferably ultraviolet light or visible light of 450 nm or less, especially on the transparent surface material. An anti-reflective layer is provided, and the anti-reflective layer or the anti-reflective layer is formed, and the bright resin film or the ultraviolet ray such as the adhesive layer is not penetrated between the anti-reflection film and the transparent surface material, and the visible light is hardened. A light source that emits light from the side can use a surface that is used when light is irradiated from the side of the transparent surface material, but an arrangement space of the light source and efficient light irradiation suitable for a specific place can be used. It is preferable to use an ultraviolet ray or an LED that emits visible light of 45 Gnm or less. The steps of illuminating and illuminating can be performed by irradiating light from the side after performing light irradiation from the side of the transparent surface material, or vice versa, or simultaneously. The light is irradiated, and the photohardening of the unhardened sealing portion and the tree sap forming light-growth moon g composition can be performed more purely, preferably by first illuminating from the side: or from the side simultaneously from the transparent surface Light irradiation on the material side... When the light passes through, and after the shot, it will be light-hardened (4), or the hardening of the photocurable resin composition may take place. 46 201206701 After the hardening of the hard layer of the resin layer is completed, the sealing portion is hardened by light irradiation from the side. [Specific example] In the manufacturing method of the embodiment, the third surface can be arbitrarily made. The material or the surface material is used. The correction device can be manufactured according to the following two methods. (α-l) The first surface material is a display element (back material), the second The face material is used as a transparent plate (4) The method of (a) the surface material is a transparent surface material (surface material) which is a protective sheet, and the second surface material is a display element (back surface material). The following method (cx-D) For example, the manufacturing method of the display device of the first drawing will be specifically described using the drawings. (Step (a)) As shown in FIGS. 3 and 4, ' along the display element 5 (&amp; face material) The peripheral portion of the display portion is formed by applying a photocurable resin composition for forming a seal portion by a dispenser (not shown) or the like to form an uncured seal portion 丨 2. The display member is provided with a transfer at the outer peripheral portion of the display member. In the manufacturing method of the present embodiment, in the manufacturing method of the embodiment, it is preferable to hold the wiring member axially while holding each surface (four), and it is preferable to use the display element as the first surface material and arrange it under the lower surface. side. (Step (bX) Next, as shown in the fifth and sixth figures, the photocurable tree (4) for resin layer formation is supplied to the rectangular region 13 surrounded by the unhardened sealing portion 12 of the display element 5Q. 14. Photoresistive layer for resin layer formation 47 201206701 The supply amount is set in advance to a space sealed by the unhardened sealing portion 12, the display element 5A, and the transparent surface material 10 (see Fig. 7). The amount of the resin layer-forming photocurable resin composition 14 can be filled. The supply layer of the resin layer-forming photocurable resin composition 14 is as shown in Figs. 5 and 6, and the display element 50 is placed flat. The lower fixing plate 18 is implemented by supplying the resin layer forming photocurable resin composition 14 in a linear, strip or dot shape by a dispenser 20 that moves in the horizontal direction. The dispenser 20 is driven by a pair of guide screws 22 And a known horizontal movement mechanism constituted by the guide screw 24 orthogonal to the guide screw 22, can be horizontally moved over the entire range of the region 13. Alternatively, instead of using the dispenser 2, a die coater can be used instead. (Step (c)) Then 'As shown in Figure 7,' will display the element 5〇 and the transparent surface material 1〇 (the second surface material) are carried into the decompression device 26. The upper plate 30 having the plurality of adsorption pads 32 is disposed on the upper portion of the decompression device 26, and the lower plate is disposed at the lower portion. The 31 ° upper fixed plate 30 is movable in the vertical direction by the air cylinder 34. The transparent surface material 10 is attached to the adsorption pad 32. The display element 50 is provided with the resin layer forming photocurable resin composition 14 facing upward. It is fixed on the lower fixed plate 31. Then, the air in the pressure reducing device 26 is sucked by the vacuum pump 28. The environmental pressure in the pressure reducing device 26 is after the reaching of a decompression environment of, for example, 15 to 40 Pa, and the transparent surface material is used. In the state in which the adsorption pad 32 of the upper plate 3 is sucked and held, the display element 50' that is standing downward toward the lower side starts and lowers the air cylinder 34. Then, the display element 50 and the transparent surface material 1 are separated from each other. Hard 48 201206701 The sealing portions 12 are overlapped to form a laminated precursor, and the laminated precursor is held for a predetermined time under a reduced pressure environment. Further, the mounting position of the display member 50 to the lower fixed plate 31 and the number of the adsorption pads 32 And transparent surface material 10 pairs The mounting position of the disk 30 and the like are appropriately adjusted in accordance with the size, shape, and the like of the display element 50 and the transparent surface material 10. At this time, the adsorption pad is an electrostatic chuck, and the instructions attached to Japanese Patent Application No. 2008-206124 are incorporated. In the electrostatic chuck holding method according to the present specification, the glass substrate can be stably held in a reduced pressure environment. (Step (d)) Next, after the inside of the pressure reducing device 26 is formed, for example, at atmospheric pressure, the pressure reducing device is removed from the pressure reducing device. The laminated precursor is taken out. When the laminated precursor is placed in an atmospheric pressure environment, the surface on the display element 50 side of the laminated precursor and the surface on the side of the transparent surface material 10 are conveniently pressed by atmospheric pressure, and are enclosed in a sealed space. The resin layer forming photocurable resin composition 14 is pressurized by the display element 50 and the transparent surface material 10. By this pressure, the resin layer forming photocurable resin composition 14 in the sealed space flows, and the entire sealed space is uniformly filled with the resin layer forming photocurable resin composition 14. Then, a light-shielding printing portion is provided on the transparent surface material, and when the uncured seal portion held by the light-shielding portion and the photo-curable resin composition for resin layer formation are cured first, as shown in FIG. The uncured seal portion 12 and the resin layer-forming photocurable resin composition 14 which are sandwiched between the light-shielding portion 55 and the display element 50 are disposed on the side of the precursor, and the display element is exposed to light (ultraviolet rays, or Irradiation of visible light of 450 nm or less, and light irradiation (violet light, visible light of (10) or less) is applied to the resin layer forming photocurable material of the resin layer formation by the light transmitting portion 56 from the side of the transparent surface material 10. The laminate __(iv) uncured seal portion 12 and the resin layer-forming photocurable resin composition 14 are cured to obtain a display device i. When the light-shielding printing portion is not provided on the transparent surface material, the laminated precursor is entirely irradiated with light from the side of the transparent surface material, and the uncured (four) and the resin layer forming light in the laminated precursor are formed. The curable resin composition 14 is cured to obtain a display device j. As described above, in the case of the method (α-l), the method of manufacturing the display device of the present embodiment is specifically made, and in the case of the other method (α·2), the display device can be manufactured in the same manner. [Operation and Effect: Manufacturing Method of Display Device] According to the method of manufacturing the display device of the present embodiment described above, it is possible to manufacture a large-area display device without generating bubbles in the resin layer. It is assumed that even if bubbles are present in the photocurable resin composition for forming a resin layer which is sealed under reduced pressure, the pressure is applied to the photocurable resin composition for forming a resin layer which is sealed under a high pressure environment before curing. The volume of the bubble can be reduced, and the bubble can be easily eliminated. For example, in the photocurable resin composition for forming a resin layer which is sealed under l〇〇Pa, the volume of the gas in the bubble can be considered to be 1/1000 at 100 kPa. Since the gas is also dissolved in the photocurable resin composition for forming a resin layer, the gas in the minute volume bubble is rapidly dissolved in the resin layer forming photocurable resin composition and disappears. In addition, even if a pressure such as atmospheric pressure is applied to the resin layer forming photocurable resin composition after sealing, the liquid resin composition 50 201206701 resin composition is in a fluid composition, and the pressure system is used. The uniform sentence is distributed on the surface of a few pieces, and the stress on the surface of the display element which is in contact with the photocurable resin composition for resin layer formation is not applied, and the risk of damage to the display element is low. Further, the interfacial adhesion force between the solar layer and the display element and the transparent surface material formed by the hardening of the photocurable resin composition formed by the tree sap layer is higher than the interfacial adhesion force using the nym. Further, the flowable resin layer is formed into a filament-curable property, and the composition is pressed against the surface of the display element or the transparent surface material, and is cured in this state, so that a higher interfacial adhesion force can be obtained. It is possible to obtain a uniform surface of the display element and the transparent face material, and then there is little reduction in the locality of the interface. Therefore, the possibility of peeling off on the surface of the resin layer is low, and the possibility of infiltration of moisture and impurities from the portion where the boundary adhesion is insufficient is also low. In addition, a method of injecting a photocurable resin composition for forming a fluid resin layer into a narrow and wide-area space between two sheets (injection method) is small, and it can be produced in a short time. A photocurable resin composition for forming a resin layer is filled. Further, the photocurable resin composition for forming a resin layer has a small viscosity limitation, and can easily fill a high-viscosity resin layer-forming photocurable resin composition. Therefore, a light-curable resin composition for forming a high-viscosity resin layer containing a higher molecular weight curable compound which can increase the strength of the resin layer can be used. In addition, the photopolymerization initiator (C2) of the photocurable resin composition for forming a resin layer is a photopolymerization initiator (Cl) having an absorption wavelength region (λ2) which is smaller than the uncured seal 51 201206701 portion. The absorption wavelength region (λΐ) is further on the long wavelength side of the photopolymerization initiator (C2), and the light irradiated from the side of the layered precursor uses wavelength light in the absorption wavelength region (λ1) Both of the wavelength light in the wavelength region (λ2) are absorbed, whereby the wavelength light in the absorption wavelength region (λ2) which is not absorbed by the photopolymerization initiator (C1) of the uncured seal portion can be sufficiently reached. The photocurable resin composition for forming a resin layer which is sandwiched between the display elements in the light-shielding portion, and the photo-polymerization initiator (C2) having the absorption wavelength region (λ2), can sufficiently perform photo-curing for resin layer formation. Hardening of the resin composition. [Operation: Hardening Resin Composition] The bonding between the display element and the transparent surface material (protective sheet) can be reduced by reducing the shrinkage ratio at the time of curing the curable resin or reducing the elastic modulus of the resin layer after curing. In addition to the stress of the display element, it is possible to effectively prevent display spots and the like from damaging the display quality. On the other hand, if the elastic modulus of the resin layer is too low, there is a possibility that the display element and the transparent surface material are displaced due to the elastic deformation of the resin layer. According to the findings of the inventors of the present invention, even if the elastic modulus of the resin layer is sufficiently high, when the display device is vertically disposed, if the self-weight of the display member is applied to the resin layer for a long period of time, the resin layer will have plasticity over time. The deformation has a possibility of causing a decrease in the accuracy of the joint position of the display element. In contrast, the curable resin composition of the present invention has a storage shear elastic modulus at the time of measurement of dynamic viscoelasticity after curing as WoMWPa, and a yarn loss is said to be in the phase (3), thereby preventing the elasticity of the resin layer. The deformation causes the positional deviation of the face materials from each other (the display element and the protection 52 201206701 plate) and reduces the stress caused by the hardening shrinkage of the resin layer, and can effectively prevent plastic deformation due to the passage of the resin layer. Causes the positional displacement of the face materials between each other (display element and protective plate).

Case 'Because the stress applied to the display element is likely to adversely affect the quality of the display, the bonding resin layer is preferably a low modulus of elasticity. Therefore, the display device using the curable resin composition of the present invention is preferably a liquid crystal display element, more preferably an lps type liquid crystal display element or a TN type liquid crystal display element. In addition, the non-hardenable component which does not harden the reaction with the curable compound (π) at the time of hardening, which is contained in the photocurable resin composition for forming a resin layer, has 8 to 3 per 丨 molecule. The non-curable oligomer of a hydroxyl group and the presence of a radical which reacts when the hardening compound (9) is hardened can suppress the loss of the resin layer loss after the hardening (plus §) and can reduce the storage shear elasticity. The modulus of the photocurable resin composition for forming a resin layer when uncured is good, and the viscosity can be lowered, and the uniformity of the curing reaction at the time of curing can be obtained. _ If the stability is not good when it is not cured, and the hardening reaction uniformity at the time of hardening is good, a resin layer having good transparency can be easily obtained. When the photocurable resin composition for forming a resin layer is not cured, the viscosity of the photocurable resin composition is low, and the occurrence of bubbles can be sufficiently suppressed. 俾 The surface interface between the surface material and the resin 53 201206701 can be easily obtained. Further, the curable resin composition of the present invention can be used not only for the use of the butyl device but also for the laminate in which the surface material is laminated via the resin layer, and the same effect can be obtained. In addition, the curable resin composition of the present invention may be a thermosetting resin composition. In this case, a known thermosetting group is used as the curable group of the curable compound. X ' is optionally contained in a known thermal polymerization initiator. In the case of the above-mentioned embodiment, the curable resin composition for forming a resin layer is thermosetting, and it is preferable that the curable resin composition for forming a sealing portion is thermosetting. In particular, since the photocurable resin composition does not require heat during hardening, it is preferable from the viewpoint that the high temperature causes less adverse effects on the face material or the like. In the case of using a photopolymerization initiator and a thermal polymerization initiator, photocuring and thermal curing may be simultaneously performed, or individual curing may be performed to improve the curability. Further, the method for producing a laminate using the curable resin composition of the present invention is not limited to the method of the above embodiment, and a known method is suitably used. [Examples] The following 'exemplifications' are examples for carrying out the effectiveness of the present invention. Examples 1 to 4, 8 and 9 are examples. Examples 5 to 7 are comparative examples. (Measurement method for storing shear modulus and loss tangent) The storage shear modulus of the resin layer after hardening and its loss tangent (tan5) are rheometers (Physica 54 201206701, manufactured by Anton Paar) MCR 301), a photocurable resin composition for forming an uncured resin layer, and sandwiched between a platform made of soda lime glass and a measuring mandrel (D-PP20/AL/S07, manufactured by Anton Paar Co., Ltd.) In a nitrogen atmosphere, a black light (FL15BL, manufactured by Nippon Electric Co., Ltd., manufactured by Nippon Electric Co., Ltd.) was applied at a temperature of 35 °C, and a dynamic shear stress of 1% was applied while irradiating light of 2 mW/cm2 for 30 minutes. The resin layer forming photocurable resin composition was cured and measured. When the resin layer-forming photocurable resin composition is cured, the position of the mandrel is automatically tracked and adjusted so that no stress is generated in the normal direction of the mandrel. The irradiation intensity was measured on a platform having a photocurable resin composition for forming a resin layer by using an illuminometer (UV intensity meter UNI METER UIT-101, manufactured by USHIO Electric Co., Ltd.). (Quantum average molecular weight) The number average molecular weight of the oligomer was determined using a Gpc apparatus (manufactured by T〇s〇H&amp;, HLC-8020).
