Abstract:
An active matrix liquid crystal display, comprising:liquid crystal arranged between a pair of substrates;a plurality of gate wirings and a plurality of source wirings provided orthogonal to each other on a surface of one of said substrates;a thin film transistor provided in the vicinity of an intersection of each of said gate wirings and each of said source wirings;a pixel electrode driven by said thin film transistor;a common electrode for applying a lateral electric field to said liquid crystal in a direction along said substrate surface in cooperation with said pixel electrode, thereby forming a plurality of pixel regions;a first insulating layer provided between said common electrode and said gate wiring, said gate wiring provided above said common electrode; anda second insulating layer provided between said pixel electrode and said gate wiring,wherein:said common electrode includes a first common electrode portion extending in a direction parallel to a direction in which said gate wiring is extended, and a second common electrode portion extending in a direction parallel to a direction in which said source wiring is extended, said first common electrode portion being provided in the vicinity of said gate wiring,said pixel electrode includes a first pixel electrode portion extending in said direction parallel to said gate wiring extending direction, and a second pixel electrode portion extending said direction parallel to said source wiring extending direction,said first pixel electrode portion is formed above said first common electrode portion, anda boundary of said first pixel electrode portion is formed within a boundary of said first common electrode portion.
