Liquid crystal panel and liquid crystal display device

摘要

A first retardation plate arranged on a front side causes light received through the a first polarizing plate from the front side to become close to circularly polarized light rotating in a first direction. Second and third retardation plates arranged on a back side cause light received through a second polarizing plate from the back side to become close to circularly polarized light rotating in a second direction opposite to the first direction while passing through both of the second and third retardation plates and the liquid crystal layer in black display period. With this structure, good image quality can be obtained even when used in outdoor.
