Abstract:
1. A display device comprising: a pair of substrates which are arranged to face each other with liquid crystal therebetween; and a plurality of pixel regions provided on a liquid-crystal-side surface of one substrate of the pair of substrates; wherein each pixel region includes a switching element, a pixel electrode to which a video signal is supplied through the switching element, and a counter electrode which generates an electric field between the counter electrode and the pixel electrode; wherein each pixel region is constituted of divided respective regions; wherein in one region of the pixel region, the counter electrode 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 is constituted of a first group of electrodes which extend in one direction and 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 first group of electrodes is overlapped to the substantially planar counter electrode in the one region in plan view; wherein in another region of the pixel region, the counter electrode is constituted of a group of electrodes which extend in one direction and 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 is constituted of a second group of electrodes which extend in the one direction and arranged in parallel in the direction which intersects the one direction in the another region so as to above the insulation film and arranged alternately with the group of electrodes of the counter electrode in the another region in plan view; and wherein a first distance between the first group of electrodes of the pixel electrode in the one region is different from a second distance between the second group of electrodes of the pixel electrode in the another region.
