LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To make the overall thickness of a device thinner without lowering the display luminance of a liquid crystal display device. SOLUTION: A cold cathode fluorescent tube 5 is provided as a back light source of a liquid crystal panel 7 and these light rays are reflected on a reflector plate 6 to be made to enter the end face of a light transmission body 1B. A reflecting sheet 2 is stuck to the back of the light transmission body 1B and a diffusing sheet 3 and a prism sheet 4 are attached to the side of emerging rays. Since the light-emitting surface of the light transmission body 1B is made to be a recessed surface shape, even when the body 1B is bent, the surface never touches the back of the liquid crystal panel 7. Moreover, since the area of the end face of the body 1B is large, the light rays of the cold cathode fluorescent tube 5 are sufficiently catched.
