Abstract:
1. An electro-optical device comprising: a substrate; a pixel electrode corresponding to a pixel on the substrate; a transistor provided between the substrate and the pixel electrode, the transistor having a semiconductor layer, a gate electrode, and an LDD structure; a first capacitor electrode provided between the pixel electrode and the transistor, the first capacitor electrode being electrically connected to the pixel electrode and the transistor; a second capacitor electrode provided between the pixel electrode and the first capacitor electrode, the second capacitor electrode being located so as to be opposite the first capacitor electrode via a capacitor insulating film, and the second capacitor electrode configured to be supplied with a predetermined electric potential; a light-shielding film provided between the pixel electrode and the second capacitor electrode, the light-shielding film being located so as to be at least partially overlapped by the semiconductor layer, and the light-shielding film being electrically connected to the second capacitor electrode via a contact hole formed in an insulating film disposed between the second capacitor electrode and the light-shielding film, wherein the second capacitor electrode and the light-shielding film are electrically connected to each other via the contact hole that is at least partially overlapped with an LDD area positioned at the pixel electrode side; and a capacitor line provided between the pixel electrode and the light-shielding film, the light-shielding film configured to be supplied with a predetermined electric potential via the capacitor line.
