Abstract:
1. A liquid crystal display device, comprising: a substrate; an insulating layer; an upper electrode layer; a plurality of gate wirings extending in a first direction and a plurality of drain wirings extending in a second direction and intersecting with the gate wirings to form a plurality of pixel regions, each pixel region including a pixel thin film transistor; and a lower electrode layer, wherein the upper electrode layer and the lower electrode layer are formed above a same major surface of the substrate with the insulating layer therebetween, wherein a plurality of openings are formed in the upper electrode layer and arranged parallel to each other so that an electric field is passed therethrough, wherein liquid crystal molecules are driven by applying voltage between the upper electrode layer and the lower electrode layer, wherein an electrode width, which corresponds to a distance between the adjacent openings, is L and the width of a minor axis of each of the openings is S, and all of the following conditions are satisfied: wherein the openings extend in a third direction that is slightly inclined relative to the first direction, and wherein the lower electrode layer is arranged to extend across a plurality of the pixel regions, and the upper electrode layer and lower electrode layers are formed above the pixel thin film transistors.
