Abstract

A vertically aligned (VA) mode liquid crystal display (LCD) comprises an upper transparent substrate, an upper electrode, an upper vertically aligned layer, a negative liquid crystal layer, a lower vertically aligned layer, a lower electrode and a lower transparent substrate; the upper electrode consists of a plurality of abreast upper stripy electrodes; the lower electrode consists of a plurality of abreast lower stripy electrodes; the upper stripy electrodes and the lower stripy electrodes are intersected with each other; an overlapping area is a pixel region; the pixel region is characterized in that in each pixel region, the upper stripy electrodes are divided into a plurality of upper stripy sub-electrodes by an upper groove formed in the wiring direction of the upper stripy electrodes; the lower stripy electrodes are divided into a plurality of lower stripy sub-electrodes by a lower groove formed in the wiring direction of the lower stripy electrodes; the electric conductivity is kept among upper stripy sub-electrodes belonging to the same upper stripy electrode; and the electric conductivity is kept among lower stripy sub-electrodes belonging to the same lower stripy electrode. The VA mode LCD can achieve a multidomain display without perspective blind area, can be design as high way drive, and has the advantages of simple structure, technological process, low cost, short design cycle and high reliability.
