The light guide plate 31 is formed of an acrylic resin or the like having a light diffusion plate 311 on a front surface and a reflection sheet 312 on a rear surface. The light source 32 is a linear light source such as a cold-cathode tube or a fluorescent lamp.

And the back surface of the frame 4 to cover the light source 32 in a non-contact manner. Such a reflection sheet 312 preferably has good light reflection efficiency and strength enough to support the light guide plate, for example, an aluminum sheet of 0.01 mm to 0.5 mm, or a white polyester of 0.15 mm to 0.5 mm. A resin sheet or the like can be used. The light guide plate 31
It is more preferable that is fitted into a storage portion (generally a through hole) of the frame 4 or fixed to a part of the frame 4. With such a configuration, it has been difficult to reduce the thickness of the conventional module to 7 mm or less.

A projection 41 that is placed on the upper surface and is in contact with the elastic member 6 is provided on the peripheral surface of the frame 4. The elastic agent 6 is made of, for example, a rod-shaped silicon rubber having a thickness of 0.5 to 2.0 mm, and is disposed along the periphery of the liquid crystal cell 1. The elastic agent 6 is arranged so that one to several elastic agents 6 are in contact with one elastic agent 6. If the drive circuit 2 is provided around the liquid crystal cell 1, there is always a gap in the arrangement of the drive circuit 2. Therefore, if the projecting portion 41 is provided on the frame 4 so as to correspond to the gap, the elastic body Anti-slip effect is further enhanced.

なった。According to the present invention, the projecting portion of the frame body prevents the elastic body from slipping. Particularly, if a driving circuit is provided around the liquid crystal cell, the driving circuit always has a gap. If the frame is provided with a protruding portion in such a manner, the effect of preventing the elastic body from slipping is further enhanced. As a result, misalignment and damage due to slippage of the liquid crystal cell during operation, which has frequently occurred in the past, were reduced.
