Patent ID: 7049634

Claim:
A camera comprising a main body and a display device attached to the main body, said display device comprising: at least one first thin film transistor formed over a substrate and electrically connected to a pixel electrode, said first thin film transistor comprising: a semiconductor layer having a pair of impurity regions and a channel region extending therebetween; a gate electrode adjacent to the channel region with a gate insulating film interposed therebetween, and a pair of LDD regions between the channel region and the pair of impurity regions, a driver circuit formed over the substrate for driving said at least one first thin film transistor, said driver circuit including at least a second n-channel TFT and a third n-channel TFT, wherein said second n-channel TFT comprises: a semiconductor layer having source and drain regions and a channel region therebetween, and an LDD region interposed between the channel region and the drain region while the source region is contiguous to the channel region; and a gate electrode adjacent to the channel region with a gate insulating film interposed therebetween, wherein the gate electrode overlaps an entire portion of the LDD region, and wherein said third n-channel TFT comprises: a semiconductor layer having a pair of impurity regions and a channel region therebetween, and a pair of LDD regions interposed between the channel region and the pair of impurity regions; and a gate electrode adjacent to the channel region with a gate insulating film interposed therebetween, wherein the gate electrode partly overlaps the pair of LDD regions.
