The vehicle display device 1 of the present embodiment is provided with a design plate 50 that covers the frame 13d of the display 13. The design plate 50 is formed in a plate shape, is provided in the display display area 23 of the dial 20, and is arranged between the speedometer 11 and the tachometer 12. One surface of the design plate 50, that is, the surface on the back surface in the depth direction Y faces the image display surface 13c of the liquid crystal panel 13a. The left side of the design plate 50 in the width direction X is formed in an arc shape along the outer shape of the speedometer 11, and the right side in the width direction X is formed in an arc shape along the outer shape of the tachometer 12, and the velocity is formed in the width direction X. It is arranged adjacent to the total 11 and the tachometer 12. The design plate 50 is formed in the same color as the dial 20 when viewed from the visual position EP, and suppresses the boundary with the dial 20 from being conspicuous. That is, the design plate 50 and the dial 20 are visually recognized as one seamless plate member whose boundary is inconspicuous when viewed from the visual position EP.

The design plate 50 is a member that is arranged on the front side of the image display surface 13c of the display 13 in the depth direction Y and covers the frame 13d of the display 13 with the image display surface 13c visible. The design plate 50 makes the boundary between the image display surface 13c and the design plate 50 inconspicuous when viewed from the visual position EP. That is, when viewed from the visual position EP, the design plate 50 makes it difficult to distinguish the image display surface 13c of the liquid crystal panel 13a from the design plate 50, and it is as if the front side of the design plate 50 in the depth direction Y is the entire image display surface. The design is enhanced by making it visible as in 13c. Hereinafter, the configuration of the design plate 50 will be described in detail.

As shown in FIG. 3, the design plate 50 has a base material 51, a matte clear layer 52, a design layer 53, a white layer 54, and a light-shielding layer 55. The base material 51 is formed in a thin plate shape and is formed in an arc shape on both sides in the width direction X (see FIG. 2). As the base material 51, for example, a smoke material (dark-colored light-transmitting material) made of polycarbonate, which is a light-transmitting fabric that transmits visible light, is used. On the base material 51, for example, a matte clear layer 52 for suppressing reflection is printed flush with the entire surface of the base material 51 on the front side in the depth direction Y, that is, on the visual position EP side by screen printing. The matte clear layer 52 may have an AR (anti-reflection) structure, a moth-eye structure, or the like. The base material 51 is formed as a smoke material as described above. The total transmittance of the base material 51, the matte clear layer 52, and the surface glass 40 is about 30% to 50%. The transmittance of the base material 51 may be adjusted by adding a pigment to the matte clear layer 52.

The base material 51 includes a first permeation portion 51a, a non-permeability portion 51b, and a second permeation portion 51c. The first transmitting portion 51a is a portion that transmits light. The image display surface 13c of the liquid crystal panel 13a is arranged on the back side of the first transmission portion 51a in the depth direction Y. The first transmission portion 51a is formed in a size that fits within the image display surface 13c of the liquid crystal panel 13a when viewed from the visual position EP side. That is, the first transmissive portion 51a has a size so that all the necessary images displayed on the image display surface 13c can be visually recognized when viewed from the visual position EP, and the frame 13d of the display 13 when viewed from the visual position EP. It is a size that cannot be seen. The first transmissive portion 51a is formed, for example, in a rectangular shape having a size slightly smaller than the image display surface 13c of the liquid crystal panel 13a. As described above, the first transmissive portion 51a has a transmittance of about 30% to 50%. The first transmission unit 51a transmits the light emitted from the image display surface 13c of the liquid crystal panel 13a to the visual position EP side.

The non-transmissive portion 51b is a portion that does not transmit light when viewed from the visual position EP, and is formed around the first transmissive portion 51a. That is, the non-transmissive portion 51b is a portion of the base material 51 other than the first permeation portion 51a and the second permeation portion 51c. The non-transmissive portion 51b is laminated with a design layer 53, a white layer 54, and a light-shielding layer 55, which will be described later. In the non-transmissive portion 51b, the frame 13d of the display 13 is arranged on the back side in the depth direction Y. The non-transmissive portion 51b covers the frame 13d of the display 13 when viewed from the visual position EP.

The design layer 53 is a layer in which a synthetic resin having a color different from white is laminated on the image display surface 13c side of the non-transmissive portion 51b, that is, on the back surface side in the depth direction Y. The design layer 53 is formed by, for example, printing a synthetic resin such as black on the image display surface 13c side of the non-transmissive portion 51b by screen printing. The design layer 53 reflects the light incident from the front side in the depth direction Y and transmitted through the base material 51 to the visual position EP side. The white layer 54 is a layer in which a white synthetic resin is laminated on the image display surface 13c side of the design layer 53, that is, on the back surface side in the depth direction Y. The white layer 54 is formed by, for example, printing a white synthetic resin on the image display surface 13c side of the design layer 53 by screen printing. The white layer 54 reflects the light incident from the front side in the depth direction Y and transmitted through the base material 51 and the design layer 53 toward the visual position EP side. As shown in FIG. 4, for example, the white layer 54 reflects the light transmitted through the gaps between the particles of the black pigment BK of the design layer 53 and the black pigment BK itself to the visual position EP side by the white pigment WH of the white layer 54. .. The light-shielding layer 55 is a layer in which a light-shielding synthetic resin that blocks light is laminated on the image display surface 13c side of the white layer 54, that is, on the back surface side in the depth direction Y. The light-shielding layer 55 is formed by, for example, printing a synthetic resin having a dark-colored light-shielding color such as black on the image display surface 13c side of the white layer 54 by screen printing. The light-shielding layer 55 blocks light emitted from the image display surface 13c of the liquid crystal panel 13a to the visual position EP side, for example.

The second transmitting portion 51c is a portion that is formed at a position different from that of the first transmitting portion 51a and transmits light. The second transmission portion 51c is a design design relating to a vehicle including various symbols, characters, decorations, etc., and is configured to include a notification symbol or the like for notifying the driver or the like of various information. The notification symbol may be configured to include, for example, a warning symbol (a warning light also called a telltale), a direction indicating symbol, and the like. The second transmissive portion 51c is a layer different from the design layer 53, the white layer 54, and the light-shielding layer 55 on the image display surface 13c side of the second transmissive portion 51c, that is, the back side in the depth direction Y, and is light. The dimming layer 56 that dims the light is laminated. The dimming layer 56 is formed by, for example, printing a dark synthetic resin on the image display surface 13c side of the second transmission portion 51c by screen printing. For example, the dimming layer 56 is formed so that the thickness in the depth direction Y is thicker than the three layers including the design layer 53, the white layer 54, and the light-shielding layer 55. In the second transmissive portion 51c, each visible light light source 70, which is a light emitting body different from the liquid crystal panel 13a, is arranged on the back side in the depth direction Y via the dimming layer 56. The second transmission portion 51c can suppress the visibility of each visible light light source 70 from the visual position EP by the dimming layer 56, and can improve the design. The second transmission unit 51c transmits visible light emitted from each visible light light source 70 and dimmed by the dimming layer 56 to the visual position EP side, and emits and displays a design design (for example, a direction indicator).

Next, a functional example of the design plate 50 according to the embodiment will be described. Here, FIG. 5 is a schematic view showing a functional example of the design plate 60 of the vehicle display device according to the comparative example, and FIG. 6 is a functional example of the design plate 50 of the vehicle display device 1 according to the embodiment. It is a schematic diagram which shows. In addition, in FIG. 5 and FIG. 6, the matte clear layer 52 and the dimming layer 56 are not shown in order to facilitate the understanding of the explanation. The design plate 60 according to the comparative example shown in FIG. 5 has a base material 61 having a first transparent portion 61a and a non-transparent portion 61b, a gray gray layer 62 laminated on the non-transparent portion 61b of the base material 61, and gray. A light-shielding layer 63 laminated on the layer 62 is provided. As shown in FIG. 7, the gray layer 62 includes, for example, the black pigment BK and the white pigment WH.

In the design plate 60, a gray gray layer 62 is laminated on the non-transmissive portion 61b of the base material 61 in order to make the boundary between the image display surface 13c of the liquid crystal panel 13a and the design plate 60 inconspicuous. Here, in the liquid crystal panel 13a, the black color (background color) when lit is visually recognized as whitish black when viewed from the visual position EP, and further, the liquid crystal panel 13a is visually recognized as whitish black when extinguished. This is because when the liquid crystal panel 13a displays black when it is lit, the light leaked from the gap between the liquid crystal cells is visually recognized. Further, since the surface of the liquid crystal panel 13a is often subjected to anti-glare treatment, when the light is turned off, the incident light (external light) transmitted through the first transmitting portion 61a is diffused and the diffused light is visually recognized. To do. In the design plate 60, a gray gray layer 62 is laminated on the non-transmissive portion 61b of the base material 61 in order to bring the color as close as possible to the whitish black color of the liquid crystal panel 13a. As shown in FIG. 5, in the design plate 60, the light incident from the front side in the depth direction Y and transmitted through the base material 61 is reflected by the gray layer 62 to the visual position EP side. Due to this reflection, the vehicle display device according to the comparative example makes the boundary between the image display surface 13c of the liquid crystal panel 13a and the design plate 60 less noticeable when viewed from the visual position EP.

On the other hand, in the vehicle display device 1 according to the embodiment, a white white layer 54 is laminated on the non-transmissive portion 51b of the design plate 50 in order to bring the color as close as possible to the whitish black of the liquid crystal panel 13a. ing. The white layer 54 reflects the light incident from the front side in the depth direction Y and transmitted through the base material 51 and the design layer 53 toward the visual position EP side. The black design layer 53 reflects the light incident from the front side in the depth direction Y and transmitted through the base material 51 toward the visual position EP side. Due to these reflections, the design plate 50 can reflect the incident light incident from the front side in the depth direction Y as a whitish black color, and the liquid crystal panel 13a becomes a whitish black color when viewed from the visual position EP. You can bring the colors closer. In particular, the design plate 50 according to the embodiment has a whitish black color formed by two layers of the design layer 53 (black layer) and the white layer 54 located on the lower layer side of the design layer 53 (FIG. FIG. 4), the design plate 60 according to the comparative example has a whitish black color formed by one layer of the gray layer 62 (see FIG. 7). As a result, the design plate 50 according to the embodiment has a structure similar to that of the design plate 60 according to the comparative example in that the liquid crystal panel 13a at the time of lighting forms a whitish black color. That is, the liquid crystal panel 13a forms a whitish black color by, for example, two layers of the liquid crystal cell and the backlight located on the back side of the liquid crystal cell, and the design plate 50 according to the embodiment is whitish. The structure that forms black is more similar than that of the design plate 60 according to the comparative example. With this configuration, the design plate 50 according to the embodiment can suppress the difference in color development (contrast) between the image display surface 13c of the liquid crystal panel 13a and the design plate 50 as compared with the design plate 60 according to the comparative example.

As described above, the vehicle display device 1 according to the embodiment includes the display 13 and the design plate 50. The display 13 displays an image on an image display surface 13c provided on the vehicle and inside the frame 13d. The design plate 50 is formed in a plate shape and is provided so as to face the image display surface 13c in the opposite direction (depth direction Y). The design plate 50 has a base material 51, a design layer 53, a white layer 54, and a light-shielding layer 55. The base material 51 has a first permeation portion 51a and a non-permeability portion 51b. The first transmitting portion 51a is formed in a size that fits within the image display surface 13c when viewed from the design plate 50 side in the facing direction (depth direction Y), and transmits light emitted from the image display surface 13c. The non-transmissive portion 51b is formed around the first transmissive portion 51a and covers the frame 13d from the design plate 50 side in the opposite direction (depth direction Y). The design layer 53 has a color different from white, and is laminated on the image display surface 13c side of the non-transmissive portion 51b. The white layer 54 is white and is laminated on the image display surface 13c side of the design layer 53. The light-shielding layer 55 is a light-shielding color that blocks light, and is laminated on the image display surface 13c side of the white layer 54.

With this configuration, the design plate 50 can reflect light at the design layer 53. Further, the design plate 50 can reflect the light transmitted through the gaps between the pigment particles of the design layer 53 and the pigment itself by the white layer 54. Due to this reflection, the design plate 50 can include white reflected light in the reflected light of the color (for example, black) of the design layer 53. With this reflected light, the design plate 50 can realize a whitish black color. As a result, the vehicle display device 1 can suppress the color difference (contrast) between the image display surface 13c of the display 13 and the design plate 50, and the boundary between the image display surface 13c and the design plate 50 is conspicuous. It is possible to realize a seamless display device that can suppress the above. Further, in the design plate 50, the distance between the back side of the base material 51 in the depth direction Y and the white layer 54 is the distance between the back side of the base material 61 of the base material 61 of the comparative example in the depth direction Y and the gray layer 62. Greater than. Due to this difference in spacing, the design plate 50 is less likely to feel the distance (difference in depth) to the image display surface 13c of the liquid crystal panel 13a than the design plate 60 of the comparative example, and the boundary between the image display surface 13c and the design plate 50. Can be suppressed from being noticeable. Further, the design plate 50 can further suppress the boundary between the image display surface 13c and the design plate 50 from being conspicuous by combining the smoked material of the base material 51. Further, the design plate 50 can suppress color variation when the white layer 54 is formed as compared with the case where the gray gray layer 62 is formed as in the design plate 60 of the comparative example, and is a non-defective product produced. The yield rate, which is a ratio, can be increased.

In the vehicle display device 1, the base material 51 has a second transmitting portion 51c formed at a position different from that of the first transmitting portion 51a and transmitting light emitted from a visible light light source 70 different from the display 13. The second transmissive portion 51c is a dimming color that dims light, and is a layer different from the design layer 53, the white layer 54, and the light-shielding layer 55 on the image display surface 13c side of the second transmissive portion 51c. It has a laminated dimming layer 56.

With this configuration, the design plate 50 can dimm the light incident on the second transmitting portion 51c from the front side in the depth direction Y by the dimming layer 56. Due to this dimming, the design plate 50 can prevent each visible light light source 70 arranged on the back side of the second transmission portion 51c in the depth direction Y from being visually recognized from the visual position EP. Further, the design plate 50 can transmit the light emitted from each visible light light source 70 to the visual position EP side via the second transmission portion 51c. Due to this transmission, the design plate 50 can display the design design 22a by light emission.

[Modification example]
Next, a modified example of the embodiment will be described. An example in which the design plate 50 and the dial 20 are formed separately has been described, but the present invention is not limited to this. The design plate 50 and the dial 20 may be integrally formed as a single plate-shaped member. In this case, for example, the design layer 53, the white layer 54, and the light-shielding layer 55 are formed in the light-shielding region.

In addition to the liquid crystal panel 13a, a plasma display, an organic EL display, or the like can also be used as the display panel.

Further, the design plate 50 has described an example in which the base material 51 is formed as a smoke material, but the design plate 50 is not limited thereto. For example, in the design plate 50, as shown in FIG. 8, even if the base material 51A is formed as a colorless transparent material and the dimming layer 57 as a smoke material is laminated on the image display surface 13c side of the first transmission portion 51a. Good. For example, the dimming layer 57 is formed so that the thickness in the depth direction Y is thicker than the three layers including the design layer 53, the white layer 54, and the light-shielding layer 55. In this case, the total transmittance of the base material 51A, the matte clear layer 52, the dimming layer 57, and the surface glass 40 is about 30% to 50%. Further, in the vehicle display device 1, the surface glass 40 may be smoked without providing the smoke material on the design plate 50. With such a smoked material, the design plate 50 can further suppress the boundary between the image display surface 13c and the design plate 50 from being conspicuous.

Further, the vehicle display device 1 may provide the design plate 50 and the dial 20 with the function of the front glass without providing the front glass 40.

Further, the liquid crystal panel 13a has described an example of displaying a color image on the image display surface 13c, but the present invention is not limited to this, and a monochrome image may be displayed on the image display surface 13c.
