摘要：
A liquid crystal display includes a liquid crystal display panel having a plurality of liquid crystal cells and aback light that irradiates the liquid crystal display panel with irradiation light. The back light includes a light source and a light guide plate having one side arranged adjacent the light source and having a planar surface with a plurality of small concaves. The planar surface is substantially parallel to a liquid crystal cell face and a plane shape of the small concaves is substantially rectangular.
