Abstract

A liquid crystal with a negative dielectric anisotropy is filled between a pair of substrates, on one of which an opposing electrode is provided while pixel electrodes and an auxiliary electrode formed around the pixel electrode are provided. The pixel electrode is a transparent electrode comprising an ITO layer; and is formed with a slit for segmenting a pixel region into a plurality of sub-pixel regions. The slit is formed from the center portion of each pixel toward and the peripheral portion thereof The auxiliary electrode is also formed under the pixel electrode at a position which corresponds to the slit Liquid crystal molecules of each sub-pixel region are so aligned as to tilt toward the center of the sub-pixel region when a voltage is applied between the pixel electrode and the opposing electrode.
