Abstract
A pair of electrodes which constitute an upper layer and a lower layer with respect to an interlayer insulation film are formed as different layers at respective pixel regions on a liquid-crystal-side surface of one substrate out of respective substrates which are arranged to face each other in an opposed manner by way of liquid crystal. At two pixel regions which are selected from the respective pixel regions, the height of background layers on which the electrodes which constitute the lower layers with respect to the interlayer insulation films are formed differs with respect to a surface of one substrate. The film thickness of the interlayer insulation film is set small with respect to the high background layer out of respective background layers which differ in height and is set large with respect to the low background layer out of respective background layers which differ in height.
