Patent ID: 7012300

Claim:
A method for manufacturing a display device comprising: forming an active layer over an insulating surface; forming an insulating film comprising a gate insulator over said active layer; forming a gate electrode over said insulating film comprising said gate insulator; forming a first interlayer insulating film over said gate electrode; removing an outermost part of said first interlayer insulting film and an outermost part of said insulating film comprising said gate insulator to expose a part of said insulating surface; forming an input wiring over said first interlayer insulating film and over the exposed part of said insulating surface; forming a second interlayer insulating film over said first interlayer insulating film and over said input wiring; removing a part of said second interlayer insulating film to form an opening in said second interlayer insulating film over said input wiring; forming an EL layer over said second interlayer insulating film; forming a conducting film comprising an anode over said EL layer and over said second interlayer insulating film and in said opening to be connected with said input wiring.
