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