Abstract:
1. A semiconductor device comprising: a gate electrode; a gate insulating film over the gate electrode; a microcrystalline semiconductor film including a channel formation region over the gate insulating film; a channel protective layer over the channel formation region of the microcrystalline semiconductor film; a source region and a drain region over the channel protective layer; a source electrode and a drain electrode over the source region and the drain region; an insulating film over the channel protective layer, the source electrode, and the drain electrode; a pixel electrode over the insulating film, the pixel electrode being electrically connected to the source electrode or the drain electrode; a spacer over the pixel electrode, the spacer overlapping with the gate electrode; a counter electrode over the spacer; and a light blocking film, a first color filter film, and a second color filter film over the counter electrode, wherein the light blocking film includes a region overlapping with the spacer, wherein each of the first color filter film and the second color filter film overlaps with the region, and wherein an entire portion of the microcrystalline semiconductor film is overlapped with the gate electrode.
