In the figure, 1 is a liquid crystal cell, 2 is a polarizing plate, 3 is a rubber connector, and 4 is a printed wiring board. A through hole 5 is formed in the printed wiring board 4 at a position facing the liquid crystal cell 1, and a light source 6 is arranged behind the through hole 5. The light emitted from the light source 6 reaches the liquid crystal cell 1 through the through hole 5 and makes the display pattern visible. FIG. 2 is a perspective view of another conventional transmissive liquid crystal display device viewed from an oblique direction. Wiring connections between the liquid crystal cell 1 and the printed wiring board 4 are made by a flexible wiring board 7. As is clear from FIGS. 1 and 2, in the conventional transmission type liquid crystal display device, a through hole 5 is formed in a position facing the liquid crystal cell 1 of the printed wiring board 4, and the wiring connection from the liquid crystal cell 1 is made to the cell. It was passed around. For this reason, the overall shape of the device has become large, making it difficult to save space.

ある。 FIG. 3 shows an embodiment of a transmissive liquid crystal display device according to the present invention, in which the transmissive liquid crystal display device is incorporated into a computer. Figure a is a side sectional view;
Figure b is a partially perspective view. Polarizing plates 2 are bonded to both sides of the liquid crystal cell 1. 5 is a support hood;
A key input section 6 is formed at one end of the support hood 5. Reference numeral 7 denotes a prism for introducing illumination light. A through hole 8 is formed in the support hood 5 located on the upper surface of the prism 7, and light indicated by a dot is incident through the through hole 8. On the surface of the prism 7 facing the liquid crystal cell 1, a transparent wiring 7a made of a transparent conductive film such as In 2 O 3 or SnO 2 is provided. The electrode terminals of the liquid crystal cell 1 are connected to the printed wiring board 4 via the rubber connector 3 and the transparent wiring 7a on the prism 7. The material of the prism 7 is, for example, glass or plastic. The prism 7 may be transparent or may be appropriately colored (a light, bright color that is preferred as a background color for a liquid crystal display pattern). Furthermore, if a metal film such as A, Ag, or Hg is applied to the rear surface A of the prism 7 and the applied film is used as a reflective film, the amount of light incident on the liquid crystal cell 1 can be increased. According to the above structure, the prism 7 installed to introduce illumination light functions as a part of the wiring board, so there is no need to open a window in the wiring board unlike in the conventional transmissive liquid crystal display device. Therefore, it is easy to route the leads for wiring connection. Note that a structure in which circuit wiring is provided above the display section via the transparent wiring 7a of the prism 7 is also possible.
