Description

  The present invention relates to a liquid crystal display panel.

  Liquid crystal display panels are used in the field of information equipment centered on computers and the field of video equipment centered on televisions. In general, a liquid crystal display panel includes an array substrate, a counter substrate, and a liquid crystal layer sandwiched between the two substrates. The array substrate and the counter substrate have a display area. Between the array substrate and the counter substrate, for example, a plurality of columnar spacers are arranged as a plurality of spacers, and a gap between both the substrates is kept constant.

  The array substrate and the counter substrate are joined by a rectangular frame-shaped sealing material disposed outside the display area of both substrates. When forming the sealing material, for example, a thermosetting resin is applied to the peripheral portion of the counter substrate, the array substrate and the counter substrate are bonded together, and the sealing material is heated and cured. In the case of the above-described liquid crystal display panel, the sealing material spreads when the array substrate and the counter substrate are bonded. In a liquid crystal display panel with a wide frame width, even if the sealing material spreads, the liquid crystal display panel is not adversely affected.

  However, in a liquid crystal display panel having a narrow frame width, such as a liquid crystal display panel for a mobile phone, if the sealing material spreads, the liquid crystal display panel is adversely affected. For this reason, there is a problem that it is difficult to narrow the frame. Therefore, a technique for suppressing the spread of the sealing material is disclosed (for example, see Patent Document 1). Thereby, the frame width of the liquid crystal display panel can be reduced.

  The array substrate 10 and the counter substrate 20 are formed in a rectangular shape. The array substrate 10 and the counter substrate 20 are arranged so that the three sides of each of the array substrate 10 and the counter substrate 20 substantially overlap. On the remaining side of the array substrate 10, the array substrate 10 extends outward from the counter substrate 20. The array substrate 10 and the counter substrate 20 are a rectangular display region R1 where both substrates overlap, and a region outside the display region R1, and a rectangular frame overlapping region R2 where the array substrate 10 and counter substrate 20 overlap. And have.

  The array substrate 10 has a glass substrate 11 as a transparent insulating substrate. A gate insulating film 12 is formed on the glass substrate 11. In the display region R1, a plurality of scanning lines 13 and a plurality of signal lines 14 are provided in a grid pattern on the gate insulating film 12 with an insulating film (not shown) interposed therebetween. Two adjacent scanning lines 13 and two adjacent signal lines 14 partition a pixel. A planarizing film 15 is formed on the gate insulating film 12, the scanning line 13, and the signal line 14. The planarizing film 15 is made of a transparent organic resin. Note that the planarizing film 15 is also formed in the overlapping region R2.

  For example, TFTs (thin film transistors) 16 are provided as switching elements near the intersections of the scanning lines 13 and the signal lines 14. The TFT 16 includes a gate electrode 16a extending a part of the scanning line 13, a semiconductor layer 16b facing the gate electrode 16a across the gate insulating film 12, a source electrode 16c connected to one region of the semiconductor layer 16b, and It has a drain electrode 16d connected to the other region. In this embodiment, the semiconductor layer 16b is formed of polysilicon (p-Si). The source electrode 16 c is connected to the signal line 14. The drain electrode 16d is connected to a pixel electrode 17 described later.

  A protruding portion 19 is formed on the planarizing film 15 in the overlapping region R2. The protruding portion 19 protrudes toward the counter substrate 20. The protrusion 19 is made of a transparent organic resin. The protrusion 19 is made of the same material as the planarization film 15.

  In the display region R1, a plurality of pixel electrodes 17 are formed in a matrix on the planarizing film 15. The pixel electrode 17 is formed of a transparent conductive film such as ITO (Indium Tin Oxide). The pixel electrode 17 is connected to the drain electrode 16 d through a contact hole formed in the planarizing film 15. The pixel electrode 17 forms a pixel. In the display region R1 and the overlapping region R2, an alignment film 18 is formed on the glass substrate 11 on which the pixel electrode 17 is formed.

  The counter substrate 20 has a glass substrate 21 as a transparent insulating substrate. In the display region R <b> 1, a light shielding layer 41 that overlaps the scanning lines 13 and the signal lines 14 is formed on the glass substrate 21. In the overlapping region R2, a rectangular frame-shaped peripheral light shielding layer 42 is formed on the glass substrate 21 as a light shielding layer. The peripheral light-shielding layer 42 is formed over the entire circumference of the overlapping region R2, and contributes to light shielding from the outside of the display region R1.

  On the glass substrate 21, the light shielding layer 41, and the peripheral light shielding layer 42, a plurality of red colored layers 40R, a plurality of green colored layers 40G, and a plurality of blue colored layers 40B are disposed. These colored layers 40R, 40G, and 40B are adjacent to each other and are arranged alternately to form the color filter 40. The peripheral portions of the colored layers 40R, 40G, and 40B overlap the light shielding layer 41.

  In this embodiment, the color filter 40 has a peripheral colored layer 40a. The peripheral colored layer 40a is provided in the overlapping region R2. The peripheral colored layer 40a is formed in a rectangular frame shape. Here, the peripheral colored layer 40a is formed of the same material as the colored layer 40R. On the color filter 40, the counter electrode 22 is formed of a transparent conductive material such as ITO.

In the display region R1, a plurality of spacers 50 are formed on the counter electrode 22 with a predetermined density. The spacer 50 is a columnar spacer.
A receiving pattern 60 is formed on the counter electrode 22 in the overlapping region R2. The receiving pattern 60 is made of the same material as the spacer 50.

  An alignment film 23 is formed on the glass substrate 21 on which the counter electrode 22, the plurality of spacers 50, and the receiving pattern 60 are formed. The counter substrate 20 has a display surface S <b> 1 on the opposite side to the array substrate 10.

  The array substrate 10 and the counter substrate 20 are arranged to face each other with a predetermined gap by a spacer 50. The array substrate 10 and the counter substrate 20 are joined to each other by a rectangular frame-shaped sealing material 70. The seal material 70 has, in part, a liquid crystal injection port 71 a formed to extend to the peripheral edges of the array substrate 10 and the counter substrate 20.

  The liquid crystal layer 30 is formed in a region surrounded by the array substrate 10, the counter substrate 20, and the sealing material 70 by a vacuum injection method. The array substrate 10 and the counter substrate 20 sandwich the liquid crystal layer 30. The liquid crystal injection port 71 a is sealed with a sealing material 80.

Next, the receiving pattern 60 will be described in detail.
The receiving pattern 60 is formed in a rectangular frame shape. The receiving pattern 60 includes a first protrusion 61, a second protrusion 62, and a third protrusion 63.

  The first protrusion 61 is provided between the peripheral portions of a pair of sides of the array substrate 10 and the counter substrate 20 that face each other. The first protrusion 61 has a gap 61a in part. Here, the 1st projection part 61 is located between the display area R1 and the 1st seal member 71 mentioned later.

  The second protrusion 62 is provided between the peripheral portions of the other pair of sides of the array substrate 10 and the counter substrate 20 facing each other. The second protrusion 62 maintains a gap between the array substrate 10 and the counter substrate 20. The height of the second protrusion 62 is the same as that of the spacer 50. Here, the 1st projection part 61 and the 2nd projection part 62 are connected and formed integrally.

  The third protrusion 63 is provided between the peripheral portions of a pair of sides of the array substrate 10 and the counter substrate 20 facing each other. The third protrusion 63 has a gap 63a. The third protrusion 63 is located on the opposite side of the display region R1 with respect to the first seal member 71.

Next, the sealing material 70 will be described in detail.
The sealing material 70 is formed in a rectangular frame shape. The sealing material 70 includes a first sealing member 71 and a second sealing member 72.

  The first seal member 71 is bonded to the peripheral edge portions of a pair of opposing sides of the array substrate 10 and the counter substrate 20. The first seal member 71 has a liquid crystal injection port 71a facing the gap portions 61a and 63a. The first seal member 71 is in contact with the first protrusion 61 and the third protrusion 63. Here, the first seal member 71 overlaps the protrusion 19.

  The second seal member 72 is bonded to the edges of the other pair of sides of the array substrate 10 and the counter substrate 20 that face each other. Here, the second seal member 72 is bonded to the edge of the array substrate 10 and the edge of the counter substrate 20 located on the same plane.

  From the above, the first seal member 71 is located between the first protrusion 61 and the third protrusion 63 formed in the overlapping region R2. For this reason, the first protrusion 61 and the third protrusion 63 can suppress the spread of the first seal member 71. Thereby, when the liquid crystal display panel shown in FIG. 1 is viewed from the front, the frame width in the vertical direction can be reduced.

  Further, since the first seal member 71 overlaps the protruding portion 19, the amount of seal can be reduced, and thereby the spread of the first seal member 71 can be suppressed. Thereby, when the liquid crystal display panel shown in FIG. 1 is viewed from the front, the frame width in the vertical direction can be reduced.

  The second seal member 72 is located on the opposite side of the display region R1 with respect to the second protrusion 62 formed in the overlapping region R2. For this reason, the 2nd projection part 62 can prevent inflow of the 2nd seal member 72 to display field R1. Thereby, when the liquid crystal display panel shown in FIG. 1 is viewed from the front, the frame width in the horizontal direction can be reduced. Then, the horizontal frame width can be made narrower than the vertical frame width.

Next, a more detailed configuration of the liquid crystal display panel will be described together with its manufacturing method.
As shown in FIGS. 1 to 4 and 5, first, a mother glass 111 as a first mother substrate having a size larger than that of the array substrate 10 is prepared as a transparent insulating substrate. According to this embodiment, the mother glass 111 has six rectangular array substrate formation regions R3 and an ineffective region R4 that is out of the array substrate formation region R3 in order to form the array substrate 10. . The mother glass 111 has a first planned dividing line e1 along the periphery of the array substrate formation region R3.

On the prepared mother glass 111, the gate insulating film 12, the scanning line 13, the signal line 14, the planarizing film 15, the TFT 16, the protruding portion 19, and the pixel electrode 17 are formed by a normal manufacturing process such as repeated film formation and patterning. Then, the alignment film 18 and the like are formed. The alignment film 18 is subjected to a predetermined alignment process (rubbing) as necessary.
As a result, six array substrates 10 are formed on one mother glass 111.

  As shown in FIGS. 1 to 3 and FIG. 6, on the other hand, in the manufacturing method of the counter substrate 20, first, a mother glass 121 as a second mother substrate having a size larger than that of the counter substrate 20 is used as a transparent insulating substrate. prepare. According to this embodiment, the mother glass 121 has six rectangular counter substrate forming regions R5 and an ineffective region R6 that is out of the counter substrate forming region R5 in order to form the counter substrate 20. . The mother glass 121 has a second planned dividing line e2 along the periphery of the counter substrate formation region R5.

  A light shielding layer 41 and a peripheral light shielding layer 42 are formed on the prepared mother glass 121. Subsequently, the colored layer 40R and the peripheral colored layer 40a are formed on the glass substrate 21, the light shielding layer 41, and the peripheral light shielding layer 42 by using, for example, a photoetching method. At this time, the colored layer 40R and the peripheral colored layer 40a are simultaneously formed of the same material. Thereafter, similarly to the colored layer 40R and the peripheral colored layer 40a, the colored layer 40G and the colored layer 40B are formed by using, for example, a photoetching method. Thereby, the color filter 40 is formed. Subsequently, an ITO film is formed on the color filter 40 to form the counter electrode 22.

  Next, using a spinner, for example, a photosensitive acrylic transparent resin is applied on the entire mother glass 121. Subsequently, the transparent resin is dried. Next, patterning is exposed to the transparent resin using a predetermined photomask. Next, after developing the exposed transparent resin, it is baked and cured.

  As shown in FIGS. 1 to 3 and FIG. 8, a plurality of columnar spacers 50 and receiving patterns 60 are thereby formed. The plurality of columnar spacers 50 and the receiving pattern 60 are simultaneously formed of the same material. The spacer 50, the first protrusion 61, the second protrusion 62, and the third protrusion 63 are each formed at the same height.

Thereafter, the alignment film 23 is formed on the mother glass 121. The alignment film 23 is subjected to a predetermined alignment process (rubbing) as necessary.
As a result, six counter substrates 20 are formed on one mother glass 121.

  Next, as shown in FIGS. 1 to 3 and 7, for example, an ultraviolet curable resin is applied as a material for forming the first seal member 71 on the mother glass 111. More specifically, the resin is applied to the protruding portion 19 in an overlapping manner. Thereby, the first seal member 71 having the liquid crystal injection port 71a is formed.

As shown in FIG. 1 to FIG. 3 and FIG. 9, subsequently, the mother glass 111 and the mother glass 121 are arranged to face each other so that the alignment film 18 and the alignment film 23 face each other, and a plurality of array substrates 10 and counter substrates 20 are arranged. The spacer 50 and the receiving pattern 60 are placed opposite to each other while holding a predetermined gap, and the counter substrate 20 and the first seal member 71 are brought into contact with each other. At this time, since the first seal member 71 is in contact with the first protrusion 61 and the third protrusion 63, the spread is suppressed.
Next, the first seal member 71 is subjected to a thermosetting process to cure the first seal member 71.

  Subsequently, the mother glass 111 is divided along the first planned dividing line e1, and the mother glass 121 is divided along the second planned dividing line e2. When dividing, for example, a scribe line is drawn along the first planned dividing line e1 and the second planned divided line e2. Thereby, the array substrate 10 is cut out from the mother glass 111, and the counter substrate 20 is cut out from the mother glass 121.

  Thereby, as shown in FIGS. 1 to 3 and FIG. 10, six empty liquid crystal cells are formed from the divided mother glass 111 and mother glass 121. Thereafter, a liquid crystal display panel is produced using these empty liquid crystal cells.

  When producing, first, for example, an ultraviolet curable resin is applied between the edges of the array substrate 10 and the counter substrate 20 as a material for forming the second seal member 72. Thereby, the 2nd seal member 72 is formed. Next, the second seal member 72 is subjected to a thermosetting process to cure the second seal member 72. Accordingly, the second seal member 72 forms a rectangular frame-shaped seal material 70 together with the first seal member 71 to join the array substrate 10 and the counter substrate 20.

  Subsequently, an empty liquid crystal display panel is carried into a vacuum chamber (not shown). Then, liquid crystal is injected into the panel from the liquid crystal injection port 71a by vacuum injection. Thereby, the liquid crystal layer 30 is formed in a region surrounded by the array substrate 10, the counter substrate 20, and the sealing material 70.

Next, an ultraviolet curable sealing material 80 is applied to the liquid crystal injection port 71a. Subsequently, the sealing material 80 is irradiated with ultraviolet rays to cure the sealing material 80.
As shown in FIGS. 1 to 3, the liquid crystal injection port 71 a is thereby sealed with the sealing material 80.
As described above, each liquid crystal display panel is completed.

  According to the liquid crystal display panel configured as described above and the method for manufacturing the liquid crystal display panel, the liquid crystal display panel includes an array substrate 10, a counter substrate 20, a liquid crystal layer 30, a receiving pattern 60, a sealing material 70, and a sealing material. 80. The receiving pattern 60 has a first protrusion 61, a second protrusion 62, and a third protrusion 63.

  The seal material 70 includes a first seal member 71 and a second seal member 72. The sealing material 70 is formed in two stages. That is, the mother glass 111 and the mother glass 121 are bonded with the first seal member 71 and the array substrate 10 and the counter substrate 20 are cut out, and then the second seal member 72 is formed.

  The first seal member 71 is located between the first protrusion 61 and the third protrusion 63. For this reason, the first protrusion 61 and the third protrusion 63 can suppress the spread of the first seal member 71. The second seal member 72 is located on the opposite side of the display region R1 with respect to the second protrusion 62. For this reason, the 2nd projection part 62 can prevent inflow of the 2nd seal member 72 to display field R1. Thereby, a narrow frame of a liquid crystal display panel can be achieved.

  The edge of the array substrate 10 to which the second seal member 72 is bonded and the edge of the counter substrate 20 are located on the same plane. Therefore, the second seal member 72 can be formed without a gap between the array substrate 10 and the counter substrate 20, and liquid crystal leakage due to poor formation of the second seal member 72 can be prevented.

The receiving pattern 60 can be formed of the same material as the spacer 50 at the same time. For this reason, the receiving pattern 60 can be formed without increasing the manufacturing process.
In addition, since the heights of the spacer 50 and the receiving pattern 60 are the same, the receiving pattern 60 is formed to maintain a gap between the array substrate 10 and the counter substrate 20. Since the receiving pattern 60 can maintain a gap between the peripheral portions of the liquid crystal display panel, it is possible to suppress a deterioration in display quality.

The protruding portion 19 overlaps the first seal member 71. For this reason, the array substrate 10 and the counter substrate 20 can be favorably bonded without applying the first seal member 71 thickly. If the first seal member 71 is thickly applied without providing the protrusions 19 and the mother glass 111 and the mother glass 121 are bonded (bonded), the first protrusions 61 and the third protrusions 63 are moved to the array substrate 10. There is a possibility that the first seal member 71 may spread beyond the first protrusion 61 and the third protrusion 63 before coming into contact with.
Due to the presence of the protrusions 19, the positioning with the counter substrate can be advantageous, and a liquid crystal panel with good performance can be formed.

  As described above, a liquid crystal display panel having a narrow frame width and a method for manufacturing the liquid crystal display panel can be obtained.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiments. For example, some components may be deleted from all the components shown in the embodiment.

  For example, as shown in FIG. 11, the receiving pattern 60 may not have the third protrusion 63. Alternatively, as illustrated in FIG. 12, the receiving pattern 60 may not have the first protrusion 61. In these cases, the receiving pattern 60 has either the first protrusion 61 or the third protrusion 63, so that the first pattern 61 and the third protrusion 63 are not provided. The spread of one seal member 71 can be suppressed.

  When the second seal member 72 is formed, it may be formed after one of the mother glass 111 and the mother glass 121 is divided. For example, as illustrated in FIG. 13, only the mother glass 121 may be divided and divided into the counter substrate 20, and then the second seal member 72 may be filled in a gap between the adjacent counter substrates 20. In this case, the second seal member 72 can be formed efficiently.

The height of the first protrusion 61 and the third protrusion 63 may be lower than the spacer 50.
The protruding portion 19, the color filter 40, the spacer 50, the receiving pattern 60, and the sealing material 70 may be formed on any one of the array substrate 10 and the counter substrate 20.
The edge of the array substrate 10 on which the second seal member 72 is formed and the edge of the counter substrate 20 may not be located on the same plane.

The spacer 50 and the receiving pattern 60 do not have to be formed of the same material.
The sealing material 70 may be formed of a thermosetting resin.
The protruding portion 19 may be formed of a material other than a transparent organic resin. For example, when the protrusion 19 and the color filter 40 are formed on the same substrate, the protrusion 19 may be formed by laminating a colored layer.
The liquid crystal display panel may not have the protruding portion 19.
