Claim:
1. A display device comprising: a substrate; a first conductive film over the substrate; a first insulating film over the first conductive film; an oxide semiconductor film over the first insulating film; a second insulating film over the oxide semiconductor film; a source wiring on and in contact with the second insulating film and electrically connected to the oxide semiconductor film through a first contact hole in the second insulating film; a common electrode over the second insulating film; a pixel electrode on and in contact with the second insulating film and electrically connected to the oxide semiconductor film through a second contact hole in the second insulating film; wherein the pixel electrode and the common electrode are formed over the same layer, wherein the pixel electrode has comb-shaped portions, wherein the first conductive film overlaps the first contact hole, wherein the first conductive film overlaps the second contact hole, and wherein the pixel electrode has a stacked-layer structure; a counter electrode over the pixel electrode.
