Patent ID: 7190420

Claim:
A display device comprising: a substrate; a plurality of parallel source lines and a plurality of parallel gate lines formed over said substrate, said source line and gate lines being arranged relative to one another to form a matrix of pixel regions over said substrate with each of said pixel regions bounded by two adjacent source lines and two adjacent gate lines; a plurality of thin film transistors formed over said substrate, with at least one thin film transistor disposed at each intersection of said source lines and gate lines such that at least one thin film transistor is located in each of said pixel regions; a first interlayer insulating film formed over said thin film transistors; a black matrix comprising a light shielding layer formed over said first interlayer insulating film, said light shielding layer being disposed to cover at least said gate lines; a conductive layer formed on a same layer as said black matrix; a second interlayer insulating film formed over said light shielding layer and said conductive layer; and a pixel electrode disposed in each of said pixel regions over said second interlayer insulating film and electrically connected to one of said thin film transistors through at least said conductive layer, wherein a periphery of said pixel electrode overlaps with said light shielding layer and at least one of said source lines.
