Patent ID: RE43782

Claim:
An active matrix type display device comprising: a substrate having an insulating surface; a plurality of pixel electrodes formed over said substrate ; with at least one thin film transistor pixel electrode of said plurality of pixel electrodes being electrically connected to said pixel electrodes, respectively at least one thin film transistor ; and a driving circuit formed over the substrate for driving said at least one thin film transistor, said driving circuit comprising: a first wiring formed over said substrate , wherein said first wiring is formed on a same layer as at least one of a source and a drain electrode of said at least one thin film transistor ; an interlayer insulating film formed over said first wiring; and a second wiring formed on over said interlayer insulating film, wherein said second wiring extends in parallel with said first wiring and is electrically connected to said first wiring via a plurality of contact holes opened in said interlayer insulating film.
