ABSTRACT:
A vertically aligned type liquid crystal display includes a liquid crystal layer disposed between pixel electrodes and a common electrode and containing vertically aligned liquid crystal molecules, the orientation of the liquid crystal molecules being controlled by an electric field. An orientation controller is formed on the common electrode at a position opposing the pixel electrode and an aspect ratio, i.e., a vertical to horizontal length ratio of the pixel electrode is set to at least 2. Alternatively, the pixel electrode is partitioned into at least two electrode regions so that each region represents a divided pixel electrode. An orientation controller is formed on the common electrode so as to correspond to each divided pixel electrode, and an aspect ratio of each divided pixel electrode is set to at least 2.
