Patent ID: 7375782

Claim:
A liquid crystal display device comprising: a pair of light transmitting substrates comprising a resin, each of the light transmitting substrates having a curved surface; a pixel thin film transistor provided over one of the pair of light transmitting substrates and comprising a semiconductor film comprising a source region, a drain region, a channel formation region provided between the source region and the drain region and a gate electrode provided adjacent to the channel formation region with a gate insulating film therebetween; an interlayer insulating film comprising an organic resin, and provided over the pixel thin film transistor; and a pixel electrode electrically connected to the drain region, and provided over the interlayer insulating film, wherein the pixel thin film transistor is bonded to another one of the pair of light transmitting substrates with a resin material, and wherein the semiconductor film contains hydrogen atoms at a density of 1×10 20 atoms cm −3 or less, and contains carbon and nitrogen atoms at a density of 5×10 18 atoms cm −3 or less, and contains oxygen atoms at a density of 5×10 19 atoms cm −3 or less.
