  In the following, the vertical direction of the display screen of the liquid crystal display panel 20 is the vertical direction, the horizontal direction of the display screen is the horizontal direction, and the direction perpendicular to the display screen (the direction perpendicular to the plane of FIG. 1) is the depth direction (front-back direction). ), The direction closer to the center of the display screen is the inner side, the direction further away from the center of the display screen is the outer side, and for the depth direction, the front side of the page of FIG. 1 is the front side, and the back side of the page of FIG. To do.

[Example of reflective display device: FIGS. 2 to 5]
2 and 3 show an example of the reflective display device of the present invention. In this example, a reflective display device is provided on the upper side of the display device shown in FIG.

  Specifically, in FIG. 2, a part of the front mask 890 is cut away, and a part of the transparent upper plate 210 is shown in cross section. In the thickness direction (vertical direction in FIG. 2), three slots 215G, 215R, and 215B are formed, and the inner frame omitted in FIG. 2 inside the transparent upper plate 210 is formed. Inside, green LEDs 82G, red LEDs 82R, and blue LEDs 82B are attached and arranged on the circuit board 81 at positions facing the slots 215G, 215R, and 215B, respectively.

  As shown in FIG. 3, the peripheral surfaces 216G, 216R, and 216B of the slots 215G, 215R, and 215B are roughened surfaces, respectively. Such grooves 215G, 215R, and 215B having rough surfaces 216G, 216R, and 216B can be easily formed by drilling or the like.

  When the transparent upper plate 210 is viewed from the front side (the front side of the paper surface of FIGS. 2 and 3), the inner surface of the outer frame upper plate 110 outside the transparent upper plate 210, the inner frame inside the transparent upper plate 210, Further, mirror thin films 213 and 214 are formed on the outer surface and the inner surface of the transparent upper plate 210 by printing so that a double-sided adhesive tape for pasting described later cannot be seen. The same applies to the transparent lower plate 220, the transparent left plate 230, and the transparent right plate 240 shown in FIG.

  The cross-sectional shape of the slots 215G, 215R, and 215B may be any of a circle, a square, a triangle, and the like.

  2 and FIG. 3, the green light 1G emitted from the green LED 82G, the red light 1R emitted from the red LED 82R, and the blue light 1B emitted from the blue LED 82B are respectively transmitted to the transparent upper plate 210. The grooves 215G, 215R, and 215B are incident on the inner surface of the transparent plate, and are irregularly reflected by the peripheral surfaces 216G, 216R, and 216B which are rough surfaces of the grooves 215G, 215R, and 215B. And the part of 215B is displayed so that it may protrude. Specifically, the illumination in this case has a soft and expansive feeling.

  As a display example of the reflective display device of this example, for example, when the power of the display device of the example of FIG. 1 (which also outputs sound by a speaker as described above) is turned on, the green LED 82G is driven and lit. Thus, when the slot 215G is displayed in green and the display device is in a standby state, the red LED 82R is driven and lit, so that the slot 215R is displayed in red and an image (video) is displayed in the mute mode. In a state where only the sound is output in the blanking mode or in the blanking mode, the blue LED 82B is driven and lit, so that the slot 215B can be displayed in blue.

  As shown in the example of FIG. 4, through holes 217G, 217R, and 217B may be formed in the transparent upper plate 210 instead of the slots 215G, 215R, and 215B as shown in FIGS. Also in this case, the peripheral surfaces of the through holes 217G, 217R, and 217B are rough surfaces.

  However, in this case, reflection films 218G, 218R, and 218B are formed on the outer surface of the transparent upper plate 210 so as to close the through holes 217G, 217R, and 217B, respectively. This is because, when the through holes 217G, 217R and 217B are formed by drilling or the like after forming the mirror thin film 213, the portions facing the through holes 217G, 217R and 217B in the mirror thin film 213 are peeled off. Conversely, when the mirror thin film 213 is formed after the through holes 217G, 217R, and 217B are formed by drilling or the like, the mirror thin film 213 cannot be formed in the portion facing the through holes 217G, 217R, and 217B. If the reflective films 218G, 218R and 218B are not formed, the light irregularly reflected by the peripheral surfaces of the through holes 217G, 217R and 217B passes to the outside of the transparent upper plate 210, and the double-sided adhesive tape described above outside the transparent upper plate 210, etc. It is because it will be absorbed in.

  By forming the reflection films 218G, 218R, and 218B, the light traveling outside the transparent upper plate 210 is reflected by the reflection films 218G, 218R, and 218B, returns to the through holes 217G, 217R, and 217B, and passes through the through holes 217G, 217G, The parts 217R and 217B are displayed.

  As shown in the example of FIG. 5, a plurality of slots 219a, 219b, 219c, 219d and 219e having different depths (lengths) are formed in the transparent upper plate 210, and the slots 219a, 219b, 219c and 219d are formed. At the position of 219e, LEDs 83a, 83b, 83c, 83d and 83e may be disposed on the inner surface side of the transparent upper plate 210.

  In this example, for example, when the output volume level is in the lowest level range, only the LED 83a is driven and lit, so that only the slot 219a is displayed, and when the output volume level is in the second lowest level range, the LED 83b. Only, or when the LEDs 83a and 83b are driven and lit, only the slot 219b or the slots 219a and 219b are displayed, and when the output volume level is in the middle level range, only the LED 83c or the LED 83a 83b and 83c are driven and lit, so that only the slot 219c or the slots 219a, 219b and 219c are displayed, and when the output volume level is in the second highest level range, only the LED 83d or the LED 83a 83b, 83c and 8 When d is driven, only the slot 219d or the slots 219a, 219b, 219c and 219d are displayed, and when the output volume level is in the maximum level range, only the LED 83e, or the LEDs 83a, 83b, 83c. 83d and 83e are driven and lit, so that only the slot 219e or the slots 219a, 219b, 219c, 219d and 219e are displayed, etc. Can be displayed.

  The above example is a case where the reflective display device is provided on the upper side portion of the display device shown in FIG. 1, but the reflective display device may be the transparent lower plate 220, the transparent left plate 230 or the transparent right plate 240 shown in FIG. It may be provided on the lower side, left side or right side of the display device. Of course, you may provide in the several edge part of a display apparatus.
