Patent ID: 7683978

Claim:
A display device comprising: a substrate; a thin film transistor formed over said substrate, said thin film transistor comprising an active layer, a gate insulating film adjacent to said active layer and a gate electrode adjacent to said gate insulating film; a gate line formed over said substrate and electrically connected to said gate electrode of said thin film transistor; a first insulating film formed over said thin film transistor and said gate line; a source line formed over said first insulating film and electrically connected to a source region of said active layer, said source line extending across said gate line; a second insulating film formed over said source line; a black matrix formed over said second insulating film; a conductive layer formed on a same layer as said black matrix; a third insulating film formed over said black matrix and said conductive layer; and at least first and second pixel electrodes formed over said third insulating film wherein said second pixel electrode is adjacent to said first pixel electrode and said first pixel electrode is electrically connected to a drain region of said active layer through at least said conductive layer, wherein said black matrix is overlapped with a periphery of said first pixel electrode at least partly, and said black matrix covers said source line and said gate line so as to completely shield said source line and said gate line from incident light in a pixel region, and wherein said second pixel electrode partly overlaps with said black matrix and said source line.
