Liquid crystal display device

Abstract

In a liquid crystal display device capable of realizing a viewing angle equivalent to the Braun tube and for controlling display with an electric field in parallel with a substrate surface, a liquid crystal display device is provided which is less in unevenness of display and homogeneous in luminance. A liquid crystal display device has a pair of transparent substrates arranged oppositely through a liquid crystal, means for regulating a direction of initial alignment of the liquid crystal, and a pixel electrode and a counter electrode formed spaced from each other in each pixel region on a liquid crystal side surface of the transparent substrate, wherein an electric field is given between the pixel electrode and the counter electrode to thereby control an amount of light transmitting in the crystal liquid between the electrodes. A light transmissive region in the pixel region has, with respect to one region set with an angle given by an electric field direction and an initial alignment direction between the pixel electrode and the counter electrode, another region having an electric field direction and an initial alignment direction that are different in the angle.
