Abstract

A liquid crystal display includes a liquid crystal panel in the pixel electrode and common electrodes formed within a pixel comprise repeating structures. The angular range of light incident from the light source is narrower along a direction of the repeating structures than along an orthogonal direction.

Claims (6)

1. A liquid crystal display comprising:

a liquid crystal panel in which at least one of a pixel electrode and a common electrode formed within a pixel comprises repeating structures;

a light source illuminating said liquid crystal panel; and

an anisotropic reflector plate arranged on a back of said light source;

wherein an angular range of light incident from said light source on said liquid crystal panel is narrower along a direction of said repeating structures of said electrode than along an orthogonal direction, and

wherein said anisotropic reflector plate has a reflection angle which varies depending on a direction of light reflection, and a direction in which said reflection angle range is relatively narrow coincides with a direction of repeating structures of said electrode.
