Patent ID: 7898605

Claim:
An active matrix device comprising: a plurality of gate lines extending in parallel and formed over a substrate; a plurality of source lines extending orthogonally to said plurality of gate lines and formed over the substrate; a plurality of pixels surrounded by said plurality of gate lines and said plurality of source lines; and at least one thin film transistor formed in each of said plurality of pixels, wherein a gate of said thin film transistor is connected to one of said plurality of gate lines and a source of said thin film transistor is connected to one of said plurality of source lines; each of said plurality of pixels comprising: a metal interconnection electrically connected to a drain of said thin film transistor, wherein said metal interconnection is positioned in a same layer as a source line of said plurality of source lines; an interlayer insulating film comprising lower and upper insulating layers formed over said source line, said metal interconnection and said thin film transistor, said upper insulating layer having an opening to expose said lower insulating layer; a light blocking conductive film formed above said thin film transistor and said metal interconnection, wherein said light blocking conductive film is in contact with said lower insulating layer in said opening; a pixel electrode formed over said thin film transistor in each of said plurality of pixels, wherein said pixel electrode is electrically connected to said the associated thin film transistor; an orientation film formed on said pixel electrode wherein a surface of the orientation film has been rubbed in one direction from one corner of each of said plurality of pixels; and an auxiliary capacitor electrically connected to said thin film transistor in parallel with said pixel electrode wherein said auxiliary capacitor has a light shielding property and covers an active region of said thin film transistor, wherein said auxiliary capacitor is positioned so as to cover a part of each of said plurality of pixels including said one corner thereof.
