Electric optical device and electronic device

Image Number 6 for United States Patent #8130333.

An electric optical device includes a transistor that includes a semiconductor layer having a source region connected to a data line, a drain region connected to a pixel electrode, and a channel region, and a gate electrode, a first light blocking film that is formed to be wider than the gate electrode and that is connected to the gate electrode via a first contact hole which is opened in a first insulating film disposed on the gate electrode, and a second light blocking film that is provided between the semiconductor layer and a substrate and is connected to the first light blocking film via a second contact hole which is opened to penetrate the first insulating film, a gate insulating film, and a second insulating film.
