Abstract:
The present invention provides a liquid crystal display device which exhibits the excellent wide viewing angle characteristic and the high-speed responsiveness. A pixel region includes a switching element which is operated in response to a scanning signal from a gate signal line, a pixel electrode to which a video signal from a drain signal line is supplied through a switching element, and a counter electrode which generates an electric field between the counter electrode and the pixel electrode. The pixel region is constituted of divided respective regions. In one region, the counter electrode made of a light-transmitting material which is formed on the center except for a slight periphery of the region below an insulation film and the pixel electrode which is constituted of a group of electrodes which extend in one direction and are arranged in parallel to each other in the direction which intersects one direction above the insulation film in a state that the group of electrodes are overlapped to the counter electrode are formed. In another region, the counter electrode which is constituted of a group of electrodes which extend in one direction and are arranged in parallel to each other in the direction which intersects one direction below the insulation layer and the pixel electrode which is constituted of a group of electrodes which extend in one direction and are arranged in parallel in the direction which intersects one direction above the insulation film and is arranged alternately with the counter electrode are formed.
