<P>PROBLEM TO BE SOLVED: To provide a light guide plate excellent in luminance even if it has a multilayer shape. <P>SOLUTION: The light guide plate has a main layer, an upper layer laminated on the upper part than the main layer, and a lower layer laminated on the lower part than the main layer. The main layer is a layer containing light diffusing particulates, the upper layer is a layer of which on the surface concavo-convex patterns are formed, and the lower layer is a layer of which on the surface concavo-convex patterns are formed. Since the light diffusion particulates are contained in the main layer inside the light guide plate, light which has advanced in the main layer is diffused in many directions by the light diffusion particulates. Accordingly, polarization of light in the advancing direction of the light by the interface between the layers can be suppressed, and a light guide plate of multilayer shape excellent in luminance can be provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
