Patent ID: 8525177

Claim:
A liquid crystal display device comprising: a first substrate; a gate electrode over the first substrate; a gate insulating film over the gate electrode; a semiconductor film comprising a channel formation region over the gate insulating film; a pixel electrode over the first substrate; a first insulating film over the pixel electrode; a conductive film over and electrically connected to the semiconductor film and the pixel electrode; a second insulating film over the first insulating film; a common electrode over the second insulating film; a liquid crystal over the common electrode; and a second substrate over the liquid crystal, wherein the first insulating film comprises silicon nitride, wherein the second insulating film comprises silicon nitride; wherein the common electrode comprises indium and tin, wherein the channel formation region does not overlapped with the common electrode, wherein the pixel electrode and the common electrode overlaps with each other at least partly, wherein the pixel electrode does not include a slit, wherein the pixel electrode and a common electrode have a transparent characteristic, wherein the common electrode is continuously provided over a plurality of pixels aligned in a source wiring direction.
