ABSTRACT:
A liquid crystal display device having openings formed in electrodes using an ECB mode to provide an improved image display quality. There is provided a liquid crystal layer having a liquid crystal director vertically aligned between a plurality of pixel electrodes and an opposed electrode. An opening without any electrode therein is formed at a predetermined position of the opposed electrodes corresponding to the respective pixel electrode. As a result, the oriented direction of the liquid crystal director in each pixel is stably determined, enabling reduction of the dispersion of the orientation of the liquid crystal direction for each pixel and to widen the viewing angle.
