Abstract
An electro-optical device includes a plurality of storage capacitors each in a corresponding pixel. Each storage capacitor includes a first capacitor electrode and a second capacitor electrode with a dielectric film therebetween. The first capacitor electrode is made of the same film as one of the semiconductor films in pixel transistors. The second capacitor electrode is provided at a layer over the gate electrode of the pixel transistors. The second capacitor electrode has a first main portion opposite to the first capacitor electrode and an extending portion that extends from the first main portion to at least partially cover the second junction region. An interlayer insulation film insulates the extending portion from the pixel transistor.
