ABSTRACT:
There is disclosed a liquid crystal display device including a liquid crystal display cell layer and a pair of polarizers arranged on the sides of respective outer surfaces of the display cell layer. The liquid crystal display device further includes a retardation compensation layer having an optical birefringence which is arranged on at least one side, in a direction of the thickness of the display cell layer and between the polarizers, which compensates a change in the retardation caused when light passes through the display cell layer so as to improve viewing angle characteristics. A direction of a maximum one of principal refractive indices of the retardation compensation layer is oriented in a direction substantially parallel to a direction of the normal perpendicular to the surfaces of transparent substrates of the display cell layer.
