  Since the dial plates 6a, 6b, 6c, and 6d described above have substantially the same structure, the following is representative of a vehicle speed display dial plate 6a for the speedometer 4a (hereinafter simply referred to as a dial plate 6a). I will explain.

  As shown in FIG. 1, the dial 6 a is provided with a hole 61 in the center and a liquid crystal opening 66 in which the liquid crystal display 36 is disposed. The hole 61 allows the rotation shaft 8a of the movement 7a to pass inside.

  As shown in FIG. 1, the dial 6a is formed in a substantially circular plane shape, and a vehicle speed display character 9a for displaying the vehicle speed as a display portion is formed along the outer periphery of the dial 6a. The characters 9a are arranged at equal intervals along the circumferential direction with the hole 61 as the center. These characters 9a are provided so as to protrude or print toward the front.

  In the case of the vehicle speed display dial 6a, the character 9a is a number indicating the speed of the automobile. The character 9a on the engine speed display dial 6b is a number indicating the engine speed. The character 9c on the fuel remaining amount display dial 6c is a character indicating the remaining amount of fuel. The character 9d of the cooling water temperature display dial 6d is a character indicating the temperature of the cooling water.

  As shown in FIG. 2, the dial 6 a includes a translucent substrate 62, a filter print layer 63 as a filter provided on the back side of the translucent substrate 62, and a diffusion plate provided on the back side of the filter print layer 63. 64.

  As shown in FIG. 1, Asahi light weight is applied to the front surface of the transparent substrate 62 excluding the characters 9a. This Asahi light weight is composed of a plurality of uneven lines 65. The concavo-convex line 65 is provided along the radial direction from the hole 61 toward the outer edge. In FIG. 1 and the like, the concavo-convex line 65 is exaggerated and greatly illustrated. The actual concavo-convex line 65 has a very small width, depth, interval, etc., and is difficult to visually recognize, and is formed more than the example shown in FIG.

The filter printed layer 63 is incident on the transparent substrate 62 established a direction of the light is transmitted through only a predetermined direction of the light out of the light incident at different incident angles from diffusion plate 64.

  According to the display device having the above-described configuration, when the dial illumination LED 16 is turned on and light is generated, the light is incident on the diffusion plate 64 through the pointer opening 32a. The light incident on the diffusion plate 64 is guided and diffused in the diffusion plate 64 and is incident on the filter printing layer 63. The filter print layer 63 transmits only light in a predetermined direction out of light incident at various incident angles from the diffusion plate 64, adjusts the direction of the light, and enters the transparent substrate 62.

  As the light incident on the transparent substrate 62 strikes the concave-convex line 65 which is the front of the Asahi light, the streaky Asahi light part 70 extending radially from the hole 61 partially shines as shown in FIG. Furthermore, the Asahi light part 70 can be further increased by the natural light LL2 (or illumination light) from the front striking the uneven line 65 of the dial.

  According to the above-described display device, the dials 6a, 6b, 6c, and 6d provided with the Asahi light weight are provided from the translucent substrate 62, and the dial illumination LEDs 16 are provided on the back of the dials 6a, 6b, 6c, and 6d. , The light LL1 can be incident also from the back of the dial 6a, 6b, 6c, 6d. Thereby, since the Asahi light part 70 can be increased compared with the case where light LL1 injects only from the front, a more novel display can be performed.

  Further, according to the display device described above, the filter print layer 63 is provided on the back surface of the dials 6a, 6b, 6c, and 6d so that the light LL1 from the dial illumination LED 16 is adjusted by the filter print layer 63 and then the character is set. The light can enter the plates 6a, 6b, 6c, and 6d. Thereby, since the Asahi light part 70 can be increased compared with the case where it injects without adjusting, a more novel display can be performed.

  In addition, according to embodiment mentioned above, the Asahi light basis weight provided the uneven | corrugated line 65 along radial shape, However, This invention is not limited to this. For example, as shown in FIG. 6, unevenness lines 65 along the circumferential direction may be provided as the Asahi light weight.

  Further, according to the above-described embodiment, the filter printing layer 63 is provided on the back surface of the dials 6a, 6b, 6c, and 6d, but the present invention is not limited to this. For example, light may be directly incident from the diffusion plate 64 without providing the filter printing layer 63.
