Patent ID: 7924384

Claim:
A display device comprising: on a liquid-crystal-side surface of one substrate of a pair of substrates which are arranged to face each other with liquid crystal therebetween, a region which is surrounded by a plurality of gate signal lines which are arranged in parallel to each other and a plurality of drain signal lines which are arranged in parallel to each other in a state that the drain signal lines intersect the gate signal lines defines a pixel region; the pixel region includes a switching element which is operated in response to a scanning signal from the gate signal line, a pixel electrode to which a video signal from the drain signal line is supplied through the 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; wherein in one region, the counter electrode made of one of a light-transmitting material and a light-reflecting material extends over the one region so as to be substantially planar at a center of the one region except at a periphery of the one region and to be 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 a direction which intersects the one direction in the one region so as to be above the insulation film in a state that the group of electrodes of the pixel electrode is overlapped to the substantially planar counter electrode in the one region in plan view, and 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 a direction which intersects the one direction in the another region so as to be below the insulation film, and the pixel electrode which is constituted of a group of electrodes which extend in the one direction and are arranged in parallel in the direction which intersects the one direction in the another region so as to be above the insulation film and is arranged alternately with the group of electrodes of the counter electrode in the another region in plan view.
