Claim:
1. A semiconductor device comprising: a semiconductor layer; a first electrode, a second electrode, and a third electrode over the semiconductor layer, wherein the second electrode is between the first electrode and the third electrode; a first insulating film over the first electrode; a second insulating film over the semiconductor layer, in a first region between the first electrode and the second electrode; a third insulating film over the semiconductor layer, in a second region between the second electrode and the third electrode; a fourth insulating film over the third electrode; a first wiring overlapping the semiconductor layer with the first electrode and the first insulating film therebetween; a second wiring overlapping the semiconductor layer with the second insulating film therebetween; a third wiring overlapping the semiconductor layer with the third insulating film therebetween; a fourth wiring overlapping the semiconductor layer with the third electrode and the fourth insulating film therebetween; a fifth insulating film over the first wiring, the second wiring, the third wiring, and the fourth wiring; and a fifth wiring over the fifth insulating film and electrically connected to the second electrode through a contact hole in the fifth insulating film, wherein the first wiring, the second wiring, the third wiring, and the fourth wiring are parallel to one another, and wherein the fifth wiring is perpendicular to the first wiring.
