Patent ID: 7652293

Claim:
An electro-optical device comprising: a plurality of thin films laminated on a substrate; a transistor formed by a part of the plurality of laminated thin films including a semiconductor layer, the semiconductor layer comprising a channel region, a source region, a drain region, a first LDD region between the channel region and the source region, and a second LDD region between the channel region and the drain region; a pixel electrode electrically connected to one of the source region and the drain region; and a light-shielding insulating layer that forms a part of the plurality of thin films, the light-shielding insulating layer being formed in an island shape that covers, in plan view, only one of the first LDD region and the second LDD region that is between the source and drain regions that is electrically connected to the pixel electrode, wherein the light-shielding insulating layer is laminated above the semiconductor layer in direct contact with the semiconductor layer.
