Abstract:
The present invention provides a liquid crystal display device which includes a pixel electrode and a counter electrode in a pixel formed on a surface of a substrate which faces liquid crystal, the counter electrode is formed below an insulation film, and the pixel electrode is formed above the insulation film, wherein the counter electrode is formed over a whole area of a center except for a slight periphery of at least the pixel, the pixel electrode is constituted of separate pixel electrodes to which a video signal which is supplied to the pixel is inputted through the separate switching elements at the same timing, and the separate pixel electrodes are respectively formed of a plurality of electrodes and the respective electrodes are alternately arranged.
