Patent ID: 7830465

Claim:
An electro-optical device comprising: a substrate; a data line over the substrate; a scanning line over the substrate, the scanning line intersecting with the data line; a pixel electrode that is provided at a position corresponding to an intersection at which the data line and the scanning line intersect with each other; a semiconductor layer including: a channel region with a channel length along a direction in which the data line or the scanning line extends; a data line side source/drain region electrically connected to the data line; a pixel electrode side source/drain region electrically connected to the pixel electrode; a first junction region formed between the channel region and the data line side source/drain region; and a second junction region formed between the channel region and the pixel electrode side source/drain region; a first insulating film that is formed in an island shape so as to cover the first junction region; a second insulating film that is formed in an island shape so as to cover the second junction region; and a gate electrode that faces the channel region through the gate insulating film and that extends onto the first and second insulating films.
