Patent ID: 8129807

Claim:
An electro-optical device comprising: a scan line extending in a first direction; a data line extending in a second direction intersecting the scan line; a pixel electrode provided in correspondence with intersection of the scan line and the data line; a semiconductor layer including: a channel region having a channel length along one of the first direction and the second direction; a source region having a source length along the second direction and electrically connected to the data line; a drain region having a drain length including a portion along the first direction and electrically connected to the pixel electrode; a first junction region formed between the channel region and the source region; and a second junction region formed between the channel region and the drain region, and bent in the drain region in correspondence with the intersection of the data line and the scan line in plan view; a gate electrode including: a main body portion facing the channel region with a gate insulating film interposed therebetween; and an enclosure portion including an L-shaped portion enclosing at least the second junction region along the portion bent in the drain region in plan view; and a sidewall portion rising or falling from the enclosure portion and including a portion arranged along the side of the second junction region.
