  Specifically, the dial plate 20 is formed in a thin plate shape and includes a light shielding region 21, a design configuration region 22, and a display display region 23. The light shielding region 21 is a region in the dial plate 20 that shields visible light emitted from a plurality of dial light sources (not shown) included in the vehicular display device 1 (hereinafter also referred to as a dial light source). It is. On the other hand, the design configuration area 22 is an area provided in the light shielding area 21 of the dial 20 and transmitting visible light emitted from the light source for the dial to the viewing position EP side. The design constituting area 22 constitutes a design symbol 22 a in the light shielding area 21 and transmits visible light emitted from a light source for a dial. The display display area 23 is an area in which the image display surface 13c of the display 13 can be viewed from the front side in the depth direction Y. The display display area 23 is, for example, an opening that is opened to the same size as a design plate 50 to be described later, and the design plate 50 is flush with the front side in the depth direction Y of the dial 20 in this opening. Provided. The display display area 23 is not limited to the opening, and may be a transmission part that transmits light as long as the image display surface 13c of the display 13 can be visually recognized together with the design plate 50.

  Here, the light source for the dial plate is a light source for design display for causing the indicator portion 15 and the like formed on the dial plate 20 to emit light, and emits visible light (visible light). Visible light is light having a wavelength in the visible light region. The wavelength in the visible light region is a wavelength that can be visually recognized by humans, and the visible light region is a component having a wavelength in the range of 360 to 830 nm, for example. The light source for the dial is configured by, for example, an LED (Light Emitting Diode) element that can emit visible light, but is not limited thereto. A plurality of light sources for the dial plate are mounted on the mounting surface on the front side in the depth direction Y of the meter board 80, and are driven and controlled via the meter board 80, and visible from the back side in the depth direction Y toward the front side.

The design composition area 22 is an area constituting these design symbols 22a, and transmits the visible light emitted from the light source for the dial so that the design symbols 22a are lit and displayed. For example, the dial plate 20 is formed of a light-shielding dark-colored ink on the base of a polycarbonate sheet of light-transmitting fabric that transmits and diffuses light having a wavelength in the visible light region, that is, visible light. 15 and the design symbols 22a constituting the design symbols 22a are formed by printing the shape corresponding to the notification symbol or the like. In the dial plate 20, the design symbol 22 a is brought into a display state by allowing visible light irradiated from the light source for the dial plate to pass through the part of each design constituting region 22 that is hollowed out. Further, the dial plate 20 is a light shielding region 21 except for the design constituent regions 22 that are hollowed out.

The facing member 30 sandwiches and holds the dial plate 20 with the meter housing 90 and exposes the display surface including the design constituting regions 22 constituting the design symbol 22a of the dial 20 to the viewing position EP side. Let

  The front glass 40 is a protective member having light permeability that transmits light, and is assembled to the front side in the depth direction Y of the facing member 30. The front glass 40 covers and protects the viewing position EP side of the display unit 10 and the dial plate 20.

  And the display apparatus 1 for vehicles of this embodiment is provided with the design board 50 which 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 disposed between the speedometer 11 and the tachometer 12. In the design plate 50, one surface, that is, the back surface in the depth direction Y faces the image display surface 13c of the liquid crystal panel 13a. The design plate 50 is formed in an arc shape along the outer shape of the speedometer 11 on the left side in the width direction X, and is formed in an arc shape along the outer shape of the tachometer 12 on the right side 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 plate 20 when viewed from the viewing position EP, and prevents the boundary with the dial plate 20 from being noticeable. That is, the design plate 50 and the dial plate 20 are visually recognized as a single seamless plate member whose boundary is not conspicuous when viewed from the viewing position EP.

  The design board 50 is a member that is disposed on the front side in the depth direction Y of the image display surface 13c of the display 13 and covers the frame 13d of the display 13 in a state where the image display surface 13c is 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, the design plate 50 makes it difficult to distinguish between the image display surface 13c of the liquid crystal panel 13a and the design plate 50 when viewed from the visual position EP, and the front side in the depth direction Y of the design plate 50 is entirely the image display surface. Designability is enhanced by making it visible like 13c. Hereinafter, the configuration of the design plate 50 will be described in detail.

  As illustrated in FIG. 3, the design plate 50 includes a base material 51, a mat 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 both sides in the width direction X are formed in an arc shape (see FIG. 2). For the base material 51, for example, a smoke material (dark color light-transmitting material) made of polycarbonate of a light-transmitting fabric that transmits visible light is used. For example, a mat clear layer 52 for suppressing reflection on the front surface side in the depth direction Y, that is, the viewing position EP side is printed on the entire surface of the base material 51 by screen printing. The mat clear layer 52 may have an AR (anti-reflection), moth-eye structure, or the like. The base material 51 is formed as a smoke material as described above. The combined transmittance of the base material 51, the mat clear layer 52, and the front glass 40 is about 30% to 50%. The base material 51 may adjust the transmittance by adding a pigment to the mat clear layer 52.

  The base material 51 includes a first transmission part 51a, a non-transmission part 51b, and a second transmission part 51c. The first transmission part 51a is a part that transmits light. In the first transmission part 51a, the image display surface 13c of the liquid crystal panel 13a is arranged on the back side in the depth direction Y. The first transmission part 51a is formed in a size that fits within the image display surface 13c of the liquid crystal panel 13a when viewed from the viewing position EP side. That is, the first transmission part 51a has a size that allows all necessary images displayed on the image display surface 13c to be viewed when viewed from the viewing position EP, and the frame 13d of the display 13 is viewed from the viewing position EP. The size is not visible. The first transmission part 51a is formed in, for example, a rectangular shape slightly smaller than the image display surface 13c of the liquid crystal panel 13a. The first transmission part 51a has a transmittance of about 30% to 50% as described above. The first transmission part 51a transmits the light emitted from the image display surface 13c of the liquid crystal panel 13a to the viewing position EP side.

  The non-transmissive portion 51b is a portion that does not transmit light when viewed from the viewing position EP, and is formed around the first transmissive portion 51a. That is, the non-transmissive portion 51b is a portion other than the first transmissive portion 51a and the second transmissive portion 51c in the base material 51. The non-transmissive portion 51b includes 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 disposed 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 viewing position EP.

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

  The second transmission part 51c is a part that is formed at a position different from the first transmission part 51a and transmits light. The second transmission part 51c is a design symbol relating to a vehicle including various symbols, characters, decorations, and the like, and includes a notification symbol for notifying a driver or the like of various information. The notification symbol may include, for example, a warning symbol (a warning light also called tell tale), a direction indication symbol, and the like. The second transmission part 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 transmission part 51c, that is, the back side in the depth direction Y, and is a light beam. A light-reducing layer 56 that diminishes the light is laminated. The light reduction layer 56 is formed by printing dark synthetic resin on the image display surface 13c side of the second transmission portion 51c by, for example, screen printing. For example, the light reducing layer 56 is formed so that the thickness in the depth direction Y is thicker than three layers including the design layer 53, the white layer 54, and the light shielding layer 55. In the second transmission part 51 c, each visible light source 70, which is a light emitter different from the liquid crystal panel 13 a, is arranged on the back side in the depth direction Y via a light reducing layer 56. The second transmissive part 51c can suppress the visible light source 70 from being viewed from the viewing position EP by the dimming layer 56, and can improve the design. The second transmission part 51c transmits the visible light irradiated from each visible light source 70 and attenuated by the light reducing layer 56 to the viewing position EP side, and displays a design pattern (for example, a direction indication symbol) by light emission.

  Next, a function example of the design plate 50 according to the embodiment will be described. Here, FIG. 5 is a schematic diagram illustrating a functional example of the design plate 60 of the vehicle display device according to the comparative example, and FIG. 6 illustrates a functional example of the design plate 50 of the vehicle display device 1 according to the embodiment. FIG. In FIGS. 5 and 6, the mat clear layer 52 and the dimming layer 56 are not shown for easy understanding of the description. The design plate 60 according to the comparative example shown in FIG. 5 includes a base 61 having a first transmission part 61a and a non-transmission part 61b, a gray gray layer 62 laminated on the non-transmission part 61b of the base 61, and a gray And a light shielding layer 63 laminated on the layer 62. For example, as illustrated in FIG. 7, the gray layer 62 includes a black pigment BK and a white pigment WH.

  In the design plate 60, a gray gray layer 62 is laminated on the non-transmissive portion 61 b of the base 61 in order to make the boundary between the image display surface 13 c of the liquid crystal panel 13 a and the design plate 60 inconspicuous. Here, the liquid crystal panel 13a is visually recognized as whiteish black when turned on (background color) when viewed from the visual position EP, and is further visually recognized as whiteish black when turned off. This is because, when the liquid crystal panel 13a displays black when it is lit, light leaked from the gap between the liquid crystal cells is visually recognized. Further, since the liquid crystal panel 13a is often anti-glare treated on its surface, incident light (external light) transmitted through the first transmission part 61a and diffused when the light is turned off are diffused to visually recognize the diffused light. It is to do. In the design plate 60, a gray gray layer 62 is laminated on the non-transmissive portion 61b of the base 61 in order to bring the color as close as possible to the white black color of the liquid crystal panel 13a. As shown in FIG. 5, the design plate 60 is reflected from the gray layer 62 toward the viewing position EP by the light incident from the front side in the depth direction Y and transmitted through the base 61. 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 inconspicuous as viewed from the viewing 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 whited black color of the liquid crystal panel 13a. ing. The white layer 54 reflects light incident from the front side in the depth direction Y and transmitted through the base material 51 and the design layer 53 to the viewing position EP side. The black design layer 53 reflects light incident from the front side in the depth direction Y and transmitted through the base material 51 toward the viewing position EP. By these reflections, the design plate 50 can reflect incident light incident from the front side in the depth direction Y as whited black, and the liquid crystal panel 13a becomes whited black when viewed from the viewing position EP. The colors can be brought closer. In particular, the design plate 50 according to the embodiment forms a whitish black color 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 (see FIG. 4), the design plate 60 according to the comparative example forms a whited black color by one layer of the gray layer 62 (see FIG. 7). As a result, the design plate 50 according to the embodiment is similar in configuration to form a whited black color by the liquid crystal panel 13a during lighting than the design plate 60 according to the comparative example. In other words, the liquid crystal panel 13a is formed in whiteish black by, for example, two layers of a liquid crystal cell and a backlight located on the back side of the liquid crystal cell, and is whitened by the design plate 50 according to the embodiment. The structure which forms black is more similar than the design plate 60 according to the comparative example. With this configuration, the design plate 50 according to the embodiment can suppress the color difference (contrast) between the image display surface 13c of the liquid crystal panel 13a and the design plate 50 more than 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 is provided in the vehicle and displays an image on an image display surface 13c provided inside the frame 13d. The design plate 50 is formed in a plate shape and is provided to face the image display surface 13c in the facing direction (depth direction Y). The design plate 50 includes a base material 51, a design layer 53, a white layer 54, and a light shielding layer 55. The base material 51 includes a first transmission part 51a and a non-transmission part 51b. The first transmission part 51a is formed in a size that can be accommodated in the image display surface 13c when viewed from the design plate 50 side in the facing direction (depth direction Y), and transmits light irradiated 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 facing direction (depth direction Y). The design layer 53 is 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 13 c side of the design layer 53. The light shielding layer 55 is a light shielding color that shields light, and is laminated on the image display surface 13 c side of the white layer 54.

  With this configuration, the design plate 50 can reflect light by the design layer 53. Further, the design plate 50 can reflect the light transmitted through the pigment particle gaps of the design layer 53 and the pigment itself with the white layer 54. By this reflection, the design plate 50 can include white reflected light in the reflected light of the color of the design layer 53 (for example, black). With this reflected light, the design plate 50 can realize a blackish white. As a result, the vehicular 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. A seamless display device that can suppress the above can be realized. Further, in the design plate 50, the distance between the back side in the depth direction Y of the base material 51 and the white layer 54 is the distance between the back side in the depth direction Y of the base material 61 of the design plate 60 of the comparative example and the gray layer 62. Bigger than. Due to this difference in spacing, the design plate 50 is less likely to feel the distance (depth difference) 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. Moreover, the design board 50 can suppress that the boundary of the image display surface 13c and the design board 50 is conspicuous by combining the smoke material of the base material 51. FIG. In addition, 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. The yield rate, which is a ratio, can be increased.

  In the vehicle display device 1, the base material 51 includes a second transmission part 51 c that is formed at a position different from the first transmission part 51 a and transmits light emitted from a visible light source 70 different from the display 13. The second transmission part 51c is a dimming color that attenuates 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 transmission part 51c. The light-reducing layer 56 is stacked.

  With this configuration, the design plate 50 can reduce the light incident on the second transmission part 51 c from the front side in the depth direction Y by the light reducing layer 56. By this dimming, the design plate 50 can suppress the visible light sources 70 arranged on the back side in the depth direction Y of the second transmission part 51c from being viewed from the viewing position EP. Moreover, the design board 50 can transmit the light irradiated from each visible light source 70 to the viewing position EP side through the second transmission part 51c. By this transmission, the design board 50 can display the design symbol 22a by light emission.

[Modification]
Next, a modification of the embodiment will be described. Although the example which forms the design board 50 and the dial 20 separately was demonstrated, it is not limited to this. The design plate 50 and the dial plate 20 may be integrally formed as a single plate-like 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 be used as the display panel.

  Moreover, although the design board 50 demonstrated the example which forms the base material 51 as a smoke material, it is not limited to this. For example, as shown in FIG. 8, the design plate 50 is formed by forming the base 51A as a colorless transparent material and laminating a light reducing layer 57 as a smoke material on the image display surface 13c side of the first transmission part 51a. Good. For example, the light reducing 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 combined transmittance of the base material 51A, the mat clear layer 52, the light reduction layer 57, and the front glass 40 is about 30% to 50%. Moreover, the display apparatus 1 for vehicles may perform a smoke process on the front glass 40, without providing the design board 50 with a smoke material. With such a smoked material, the design plate 50 can further suppress the conspicuous boundary between the image display surface 13c and the design plate 50.

  Moreover, the display apparatus 1 for vehicles may provide the design plate 50 and the dial plate 20 with the function of the front glass without providing the front glass 40.

  Moreover, although the liquid crystal panel 13a demonstrated the example which displays a color image on the image display surface 13c, it is not limited to this, You may display a monochrome image on the image display surface 13c.
