While the display substrate 21 has translucency, the printed layer 22 has light shielding properties, and the display member 16 has portions having different translucency depending on the application mode of the printed layer 22. Existing.

  The light blocking ratio by the print layer 22 is set by the color shade. The printing layer 22 of the present embodiment has a silver-based printing color, and the shading rate is higher as the saturation and brightness are lower. That is, the light shielding rate is higher in the portion of the silver-based color with low saturation and lightness than the color portion with high saturation and lightness.

  As shown in FIGS. 1 and 2, the display member 16 includes a decorative plate portion 31 extending obliquely forward toward the outer peripheral side, and an outer peripheral plate portion 32 provided on the outer peripheral side of the decorative plate portion 31. ing.

  In the display member 16, the light shielding rate of the printing layer 22 is set high as a whole, and light from the liquid crystal panel 11 is not transmitted. Further, the printing layer 22 is formed by performing printing so that the saturation and brightness are uniform. In the decorative plate portion 31, the print layer 22 may be formed by gradation printing so that the saturation and the brightness gradually increase as the outer plate 32 approaches.

  The decorative plate portion 31 is provided with an elongated decorative line 33 extending in the depth direction of the display member 16. The decoration line 33 extends forward from the rear end portion of the decoration plate portion 31 to a position that does not reach the front end portion, and has a uniform width dimension. A plurality of decoration lines 33 are arranged at predetermined intervals along the circumferential direction of the decoration plate portion 31.

  The decoration line 33 is provided with respect to the inner peripheral surface 31a of the decoration board part 31 because the color of the printing layer 22 is partially different. The decoration line 33 is, for example, white, and the translucency of the decoration line 33 is higher in the printed layer 22 than in other parts. For this reason, when an image is displayed on the liquid crystal panel 11, the decoration line 33 emits white light by the light from the liquid crystal panel 11.

  The liquid crystal panel 11 is formed in a rectangular shape, and the entire front surface thereof is a display surface 11a. In this case, the rear end portion of the display member 16 is disposed on the front side of the display member 16, and the entire display surface 11a is not exposed forward, but an intermediate portion of the display surface 11a is exposed forward.

The electrode is composed of a transparent electrode provided for each pixel, and a voltage applied to the electrode is controlled by a thin film transistor. The color filter substrate has a red filter, a green filter, and a blue filter, and each filter is arranged for each pixel (each electrode). In addition, a thin film transistor (TFT) (not shown) that turns on and off each pixel is provided. The polarizing film is a filter that transmits light that vibrates in a predetermined direction and restricts the vibration direction of the light to a predetermined direction. The pair of polarizing films are arranged so that the vibration direction is shifted by 90 degrees. This TFT liquid crystal panel has a known structure.

  The protective sheet 15 is formed of a translucent sheet material, and clear printing that restricts reflection of light is performed on the surface of the sheet material. The protective sheet 15 is affixed to the entire display surface 11a of the liquid crystal panel 11, and has the same shape and size as the display surface 11a.

  The vehicle display device 10 includes a decorative ring 41 that extends along the rear end of the display member 16. The decoration ring 41 is an elliptical annular member formed of a smoke-colored light guide and has translucency. The outer peripheral surface of the decorative ring 41 is formed by a plating layer deposited by plating, and this plating layer has a silver-based metallic color. The plated layer has translucency and allows light to enter and exit the interior of the decorative ring 41.

  The decoration ring 41 is overlaid on the front surface of the protective sheet 15, so that the decorative ring 41 protrudes forward from the protective sheet 15. Here, the rear end of the display member 16 is spaced forward from the protective sheet 15, and the protruding dimension of the decorative ring 41 from the protective sheet 15 is greater than the distance of the display member 16 from the protective sheet 15. Is also getting bigger. The decoration ring 41 corresponds to a light emitting unit, and the liquid crystal panel 11 corresponds to an image display unit.

  As shown in FIGS. 3 and 4, the liquid crystal panel 11 includes an information area 51 for displaying an information image for informing vehicle information and a decoration area for displaying a decoration image for causing the decoration ring 41 to emit light. 52. The information area 51 has a substantially elliptical shape, and the decoration area 52 has a substantially elliptical ring shape extending along the peripheral edge of the information area 51. In the decorative region 52, the inner peripheral end is substantially elliptical, while the outer peripheral end is rectangular. The information image corresponds to the first image, and the information area 51 corresponds to the first area. Further, the decorative image corresponds to the second image, and the decorative region 52 corresponds to the second region. In FIG. 3, the decoration region 52 is illustrated by dot hatching for the liquid crystal panel 11.

  In the information area 51, a speedometer image that displays the traveling speed of the vehicle, a tachometer image that displays the rotational speed of the vehicle engine, a navigation image, an image that appears on the side mirror, a warning image, and the like are displayed as information images. In the decoration area 52, an image having the same color as the whole is displayed as a decoration image. For the decorative image, the color tone and brightness of the image can be selected.

  As shown in FIG. 3, the decoration ring 41 extends along the inner peripheral end of the decoration region 52. The liquid crystal panel 11 includes a ring main body 42 disposed on the front side, and a rear extending portion 43 extending rearward from the ring main body 42. The ring main body 42 has a semispherical cross section as a whole, and is surrounded by arcs and strings. In the ring main body 42, the rear surface is a facing surface facing the display surface 11a of the liquid crystal panel 11, and the front surface is a curved surface curved forward. In the decorative ring 41, when light is incident on the rear surface of the ring body 42 from the liquid crystal panel 11, the entire curved surface of the ring body 42 has substantially the same brightness because the light travels through the interior and becomes scattered light. Lights on.

  The ring body 42 includes a facing portion 42a facing the decorating region 52 of the liquid crystal panel 11, an inner peripheral portion 42b disposed on the inner peripheral side of the facing portion 42a, and an outer peripheral portion disposed on the outer peripheral side of the facing portion 42a. 42c. The inner peripheral part 42 b protrudes from the decorative area 52 to the inner peripheral side, and faces the information area 51 of the liquid crystal panel 11. The outer peripheral portion 42 c protrudes from the decorative region 52 to the outer peripheral side, and faces the side surface portion of the light shielding case 35. In this case, the facing portion 42 a, the inner peripheral portion 42 b, and the outer peripheral portion 42 c are arranged side by side in the width direction of the ring main body 42. The inner peripheral part 42b corresponds to the inner protruding part, and the outer peripheral part 42c corresponds to the outer protruding part.

  The ring body 42 has a support recess 44 that supports the rear end of the display member 16. The support recess 44 is formed by recessing the intermediate position of the curved surface toward the rear in the width direction of the ring body 42, and the decorative plate portion 31 of the display member 16 is inserted into the support recess 44 from the front. In this case, a part of the ring main body 42 on the inner peripheral side with respect to the support recessed part 44 is in a state of being overlapped with the inner peripheral surface 31 a of the decorative plate part 31. That is, the decoration ring 41 is in a state of straddling the liquid crystal panel 11 and the display member 16.

  The support recessed part 44 is inclined according to the inclination angle of the decorative plate part 31 and extends obliquely forward toward the outer peripheral side. The support recess 44 extends along the longitudinal direction of the ring body 42, and its width dimension gradually increases from the base end portion toward the open end portion. In this case, the width dimension of the base end portion is substantially the same as the thickness dimension of the decorative plate portion 31, and the decorative plate portion 31 is fitted in the support recess 44.

  The outer peripheral part 42c protrudes to the outer peripheral side of the light shielding case 35, and the rear extension part 43 extends from the protruding part. The rear extension 43 faces the outer peripheral surface of the light shielding case 35, and a spacer member 45 is provided between the rear extension 43 and the light shielding case 35. The spacer member 45 is a member such as rubber having flexibility, and is in close contact with the opposing surfaces of the rear extension 43 and the light shielding case 35. Further, the outer peripheral portion 42 c is in a state of being overlaid on the side end surface 11 c of the liquid crystal panel 11 via the light shielding case 35 and the spacer member 45. The rear extension 43 corresponds to the light emission extension.

  Between the ring main body 42 and the protective sheet 15, a regulation layer 46 that regulates the luminance of light emitted from the liquid crystal panel 11 is provided. The regulation layer 46 is a printing layer formed by hot stamping or the like, and has a higher light shielding rate than the ring body 42. For this reason, when the decoration ring 41 emits light by the light of the liquid crystal panel 11, the luminance of the decoration ring 41 tends to be smaller than the luminance of the information area 51 of the liquid crystal panel 11. In this case, it is suppressed that the visibility of the information image displayed on the information area 51 is reduced by the light of the decoration ring 41. Further, the regulation layer 46 is in a state of straddling the boundary portion between the facing portion 42 a and the inner peripheral portion 42 b in the ring body 42, that is, the boundary portion between the information region 51 and the decoration region 52 in the liquid crystal panel 11. .

  The ring body 42 is spaced forward from the liquid crystal panel 11 by the thickness of each of the protective sheet 15 and the regulation layer 46, and the width dimension W of the inner peripheral portion 42 b of the decorative ring 41 is equal to that of the protective sheet 15 and the liquid crystal. It is larger than the separation distance L from the panel 11. In this case, when the boundary between the information area 51 and the decoration area 52 on the display surface 11a of the liquid crystal panel 11 and the inner peripheral side end on the rear surface of the ring body 42 are connected by a straight line, this straight line and the display surface The angle Θ between 11a is smaller than 45 degrees. For this reason, even when a user such as a driver visually recognizes the decoration ring 41 from the inner peripheral side, the decoration image of the decoration region 52 directly enters the user's field of view without using the decoration ring 41. Is less likely to occur.

  The regulation layer 46 extends to the outer peripheral side from the base end portion of the support concave portion 44, and the outer peripheral side end portion of the regulation layer 46 is disposed at the rear position of the open end portion of the support concave portion 44. In this case, the regulation layer 46 extends to the rear side of the decorative plate portion 31, and light that directly enters the decorative ring 41 without passing through the regulation layer 46 from the decorative region 52 is displayed on the decorative plate. It is difficult to occur that it is discharged to the inner peripheral side of the portion 31.

  When the light hitting the rear surface of the decorative plate portion 31 from the decorative ring 41 is emitted forward through the decorative line 33, the decorative line 33 is displayed in a luminous manner. Here, the light blocking rate of the regulation layer 46 is set so that the luminance of the decoration ring 41 is substantially the same as the luminance of the decoration line 33. Note that not all of the decoration region 52 is covered with the regulation layer 46, and the luminance of the decoration line 33 is appropriately secured by the uncovered portion.

  The electrical configuration of the vehicle display device 10 will be briefly described. The vehicle display device 10 includes a control device provided on the circuit board 17, and a liquid crystal panel 11 is connected to the control device. In addition, various sensors and an information acquisition unit are connected to the control device, and the control device determines safety regarding vehicle travel based on the detection results of these sensors and the acquisition results of the information acquisition unit. If the safety is properly secured, a decorative image is displayed in a safe color such as white in the decorative region 52 of the liquid crystal panel 11, and the decorative ring 41 and the decorative line 33 are emitted in a safe color. Let

  On the other hand, when the safety is lowered, a decoration image is displayed in the decoration area 52 with a warning color such as red having a tone different from the safety color, and the decoration ring 41 and the decoration line 33 are displayed with a warning color. Light up with. In this case, the brightness of the decorative image is set higher than that in the case where safety is appropriately secured, and the bordering effect of the information image by the decorative ring 41 is enhanced. In this case, in the information area 51, a warning image for warning that the safety emperor has fallen is displayed as an information image.

  The operational effects of the first embodiment described so far will be described below.

  According to the first embodiment, when a decoration image is displayed in the decoration region 52 of the liquid crystal panel 11, the decoration ring 41 emits light by the light of the decoration image. For this reason, in addition to the presence of the decoration ring 41 itself, the appearance of the vehicle display device 10 can be enhanced by the light emission of the decoration ring 41 using the light of the decoration image. In addition, since the decoration ring 41 has a three-dimensional structure, the display surface 11a of the liquid crystal panel 11 creates a sense of depth and perspective as if the portion overlapping the decoration ring 41 protrudes forward. Can do. Furthermore, in the liquid crystal panel 11, since the information area 51 is bordered by the decoration ring 41, it is possible to realize a configuration in which the information image displayed in the information area 51 is easily noticeable. In this case, the user can promptly recognize necessary information as an information image according to the situation. Moreover, since it is not necessary to install a dedicated light source for causing the decoration ring 41 to emit light, the vehicle display device 10 can be provided at a low cost by the amount not using the dedicated light source.

  According to the first embodiment, in the decoration area 52, a decoration image different from the information image is displayed. For this reason, unlike the case where the information image is displayed with the information area 51 and the decoration area 52 as one area, for example, the light emission mode of the decoration ring 41 can be clearly different from the information image. Therefore, the bordering effect of the information image by the decoration ring 41 can be enhanced.

  According to the first embodiment, the inner peripheral portion 42 b of the decoration ring 41 protrudes from the decoration area 52 to the information area 51. For this reason, even when the user visually recognizes the information area 51 from the inner peripheral side of the decoration ring 41, the decoration image displayed in the decoration area 52 is visually recognized by the user without passing through the decoration ring 41. Does not occur. Therefore, it can suppress that the appearance of the display apparatus 10 for vehicles falls resulting from having seen a decoration image from between an information image and the decoration ring 41. FIG.

  According to the first embodiment, the ring main body 42 is overlaid on the display surface 11 a of the liquid crystal panel 11, and the rear extension 43 is overlaid on the side end surface 11 c of the liquid crystal panel 11. 41 can be stabilized. In this case, since the decorating ring 41 is not easily displaced with respect to the decorating region 52, the appearance of the vehicle display device 10 is deteriorated due to the misalignment, and the decorating ring 41 is mounted on the liquid crystal panel 11. It is possible to suppress the rattling against.

  According to the first embodiment, the luminance of light incident on the decoration ring 41 is reduced by the restriction layer 46, so that the luminance of light emitted from the decoration ring 41 can also be reduced. For this reason, it can suppress that the brightness | luminance of the decoration ring 41 becomes higher than the information image of the information area 51 excessively. That is, it can suppress that the visibility of an information image falls with the light emission of the decoration ring 41, and that an information image becomes inconspicuous.

  According to the first embodiment, since the decorative ring 41 supports the rear end of the display member 16, a dedicated member for supporting the rear end of the display member 16 is provided on the front side of the liquid crystal panel 11. There is no need to place them. Therefore, it can suppress that the appearance of the display apparatus 10 for vehicles falls by presence of the exclusive member, and the information area 51 becomes small by the part which installs an exclusive member.

  According to the first embodiment, the rear end portion of the display member 16 is in a state where it enters the support recess 44 of the decoration ring 41, so that light from the decoration ring 41 is transmitted to the inner peripheral side of the display member 16. And can be discharged to both the outer peripheral side. In this case, the appearance of the front side of the liquid crystal panel 11 can be enhanced by the light emitted to the inner peripheral side of the display member 16, and the decoration line 33 is caused to emit light depending on the light emitted to the outer peripheral side of the display member 16. Thus, the appearance of the display member 16 itself can be improved. That is, the appearance of both the inner peripheral side and the outer peripheral side of the display member 16 can be enhanced by the light of the decoration ring 41.

  According to the first embodiment, in the decorative plate portion 31, since the plurality of decorative lines 33 extend forward, the vehicle display device 10 exceeds the extension dimension of the decorative plate portion 31 from the liquid crystal panel 11. Can create a sense of depth and perspective. In addition, since the decorative lines 33 give a feeling of convergence toward the inner peripheral side of the display member 16, it is possible to make the sense of depth and the sense of perspective remarkable.
