Claim Text:
1. A display device comprising: a first substrate; a first conductive film on and in contact with the first substrate; a first insulating film on and in contact with the first conductive film; a semiconductor film comprising a channel region on and in contact with the first insulating film; a gate insulating film over the semiconductor film; a gate over the gate insulating film; a second insulating film over the gate; a source wiring over the second insulating film and in contact with the semiconductor film through a first contact hole in the gate insulating film and the second insulating film; a second conductive film over the second insulating film and in contact with the semiconductor film through a second contact hole in the gate insulating film and the second insulating film; a third insulating film over the source wiring and the second conductive film; a pixel electrode over the third insulating film and in contact with the second conductive film through a third contact hole in the third insulating film; a common electrode below the pixel electrode with the third insulating film interposed therebetween; an alignment film over the pixel electrode and the common electrode; a liquid crystal over the alignment film; and a second substrate over the liquid crystal, wherein the first conductive film is in a floating state, wherein the first conductive film and the gate are overlapped with each other with the channel region interposed therebetween, wherein the first insulating film is a silicon oxide film, wherein the semiconductor film is a polysilicon film, wherein the gate and the common electrode are overlapped with each other, wherein the source wiring and the first conductive film are overlapped with each other, wherein the first conductive film and the second conductive film are overlapped with each other, wherein the third contact hole does not overlap the common electrode, wherein the pixel electrode has comb-shaped portions, and wherein a space is located between the comb-shaped portions of the pixel electrode.
