Abstract:
1. A semiconductor device comprising: a gate electrode and a first electrode on an insulating surface; a first insulating film over the gate electrode and the first electrode; a semiconductor layer over the first insulating film; a source region and a drain region over the semiconductor layer; a source electrode and a drain electrode over the source region or the drain region; a second insulating film over the source electrode and the drain electrode; an opening portion in the second insulating film; and a pixel electrode over the second insulating film, wherein the pixel electrode is connected to the drain electrode via the opening portion, wherein the first electrode, the semiconductor layer and the drain region overlap with the opening portion of the second insulating film, and wherein a cavity is provided between the gate electrode and the first electrode, and between the insulating surface and the first insulating film.
