Patent ID: 7259429

Claim:
A semiconductor display device comprising: at least a first thin film transistor and a second thin film transistor; a first interlayer insulating film formed so as to cover the first thin film transistor and the second thin film transistor; first, second and third wirings formed over and within the first interlayer insulating film; a second interlayer insulating film formed over the first interlayer insulating film; fourth and fifth wirings formed over and within the second interlayer insulating film; and a display element formed over the second interlayer insulating film and connected to the fifth wiring, wherein the first wiring is connected to a first terminal and a gate electrode included in the first thin film transistor through first and second contact holes formed in the first interlayer insulating film, wherein the second wiring is connected to a second terminal included in the first thin film transistor through a third contact hole formed in the first interlayer insulating film, wherein the third wiring is connected to a first terminal or a second terminal included in the second thin film transistor through a fourth contact hole formed in the first interlayer insulating film, wherein the fourth wiring is connected to the second wiring through a fifth contact hole formed in the second interlayer insulating film, and wherein the fifth wiring is connected to the third wiring through a sixth contact hole formed in the second interlayer insulating film.
