Abstract

PURPOSE:To make a light transmission plate thin by two-dimensionally disposing a liquid crystal panel and a driving element for the liquid crystal panel on a substrate and constituting plural light diffusion plates. CONSTITUTION:The this light transmission plate 7 having a flat surface 71 on its surface and an irregular reflection surface 72 on its back surface is provided on the back side of a plate-like liquid crystal module 1 which is obtained by two-dimensionally disposing the liquid crystal panel 5 and the driving element 6 for the liquid crystal panel 5 on the substrate 4. Then, a reflector 8 and plural light diffusion plates 9a and 9b are laminated and closely stuck on the irregular reflection surface 72 side and on the flat surface 71 side of the plate 7 respectively. A light source for irradiating the plate 7 with light is provided on the side of the side end of the plate 7. Therefore, clearance, etc., is not necessitated and the irregular reflection surface 72 which is projected on the back is hidden by the light diffusion plate 9b superposed on an upper layer part. Thus, the light transmission plate 7 is made thin.

(Problem to be Solved by the Invention) However, in the above conventional structure, first of all, the driving element (A) is mounted using a printed circuit board (P), and this printed circuit board (P) is mounted on a light transmitting plate (E). ), the overall thickness becomes thicker by the amount that the substrate (P) is placed on the back side, and there is a problem in that there is a limit to how thin the substrate (P) can be made. In this point,
Place the printed circuit board (P) on the back side of the light transmitting plate (E),
They are arranged on the outer side of the transparent plate (E) or, for example, inside the main body case on the keyboard side, and these external parts are connected between the substrate and the liquid crystal module (D) by a flexible tube (K).
), but even if there is an improvement in the thickness of the display case, the flat surface of the case may become wider, or other cases may become larger, resulting in new problems in other areas. The disadvantage is that it imposes size constraints.

Secondly, since only one light diffusing plate (G) is inserted, there is a limit to how thin the light transmitting plate (E) can be made.
Also from this point of view, there is a limit to reducing the overall thickness. In other words, as the light transmitting plate (E) becomes thinner, the diffuse reflection surface (F) such as a dot pattern formed on the back surface becomes thinner than the light diffusing plate (G).
) and the thickness of the light transmitting plate (E) and appear on the back of the liquid crystal panel, making the screen extremely difficult to see, especially if they appear behind small letters. Therefore, it is necessary to ensure the thickness of the light transmitting plate (E) to a certain extent or more, which increases the overall thickness.

Secondly, since the light diffusing plates (9a) and (9b) are configured with a plurality of sheets, it is possible to reduce the thickness of the light transmitting plate (7). By thinning the wall,
Furthermore, the overall thickness can be made thinner. In other words, when two light diffusing plates are provided, since the pear pattern is formed on the surface of each light diffusing plate (9a) (9b), the light diffusing plate (7) is made thinner and the light of the first one is Dots (7
Even if 2a) is captured, the second light diffusing plate (9b) layered on top of it will obscure the dot (7) that appears behind it.
2a) can be hidden, and since there is no problem in making the light transmitting plate (7) thinner, it is possible to further reduce the thickness. In addition, two light diffusing plates (9a) (9b)
), if the illuminance of the light irradiated to the liquid crystal panel (5) decreases slightly, this can be compensated for by slightly increasing the gas pressure of the light source (3) compared to the conventional one-panel configuration.
