PROBLEM TO BE SOLVED: To cope with limitation of increasing a light guide plate or a diffusion plate, even though the same with high performance having fine patterns can be produced by injection molding. SOLUTION: The laminated light guide plate and the laminated diffusion plate are provided by joining films having fine structures such as prisms, fine pyramid structures, and reflection patterns and a transparent substrate. Respective components can be formed by a continuous process with high productivity, and they can be easily increased in size. Further, warps caused by environmental changes can be lessened by joining the films made of a base material with the same material quality on both surfaces of the transparent substrate. A highly-reliable liquid crystal display device capable of having a high-quality image display on a large screen can be achieved. COPYRIGHT: (C)2010,JPO&INPIT |
