Patent ID: 8178880

Claim:
A semiconductor device comprising: a gate electrode and a source wiring formed over an insulating surface; a first insulating film formed over the gate electrode and the source wiring; a semiconductor film formed over the first insulating film; wherein the semiconductor film comprising a channel region, a source region and a drain region, a source electrode formed over the first insulating film; and a first electrode formed over the first insulating film; a second insulating film formed over the first electrode; a pixel electrode formed over the first insulating film; a second electrode formed over the second insulating film; wherein the source electrode is electrically connected to the source region and wherein the source electrode is electrically connected to the source wiring through at least an opening in the first insulating film, and wherein the pixel electrode is electrically connected to the drain region, wherein the second electrode is electrically connected to the drain region, wherein the first electrode is overlapped with the second electrode.
