Liquid Crystal Display

Abstract

A liquid crystal display has a pixel array including first and second pixel electrodes. Each of the first pixel electrodes is divided into at least two first sub-pixel electrodes in two pixel areas sharing a corner or an edge. Similarly, each of the second pixel electrodes is divided into at least two second sub-pixel electrodes in two pixel areas sharing a corner or an edge. The polarities of the first and the second electrodes are opposite. The first and the second pixel electrodes are arranged alternatively to allow at least one first sub-pixel electrode and at least a second sub-pixel electrode to be located in each pixel area.
