Abstract
A light guide plate having a rectangular plate-like shape includes a light entrance surface, a light exit surface, an opposite plate surface, and a light reflection pattern. The light entrance surface is a peripheral surface. The light exit surface is a plate surface. The opposite plate surface is opposite from the light exit surface. The light reflection pattern includes light reflection portions having distribution densities different from section to section of the opposite plate surface. The distribution densities are defined such that a difference between the distribution density in a section in the middle row and each end column and the distribution density in a section in the middle row and the middle column is larger than a difference between the distribution density in a section in the end row and each end column and the distribution density in the section in the end row and the middle column.
