<P>PROBLEM TO BE SOLVED: To provide a light guide plate which reduces a clearance of dots between meshes, and reduces luminance unevenness. <P>SOLUTION: The light guide plate includes a reflecting surface and an emission surface opposite to each other. Dots are arranged in a plurality of meshes partitioned on the reflecting surface. In a light guide plate in which light input from a light source arranged at least one side surface side intersecting with the reflecting surface is reflected from the dots and is emitted from the emission surface, maximum density arrangement of dots in the mesh is achieved by zigzag arrangement, and the mesh has a regular triangular shape or a polygonal shape formed by combining regular triangles. <P>COPYRIGHT: (C)2010,JPO&INPIT |
