Abstract
A liquid crystal device as an electrooptical device includes a TFT as a transistor, a pixel electrode provided correspondingly to the TFT, a storage capacitor in which a first capacitance electrode, a capacitance insulating layer, and a second capacitance electrode are stacked in order, and a contact portion as a first contact portion configured to electrically connect a semiconductor layer of the TFT and the pixel electrode. In the liquid crystal device, the second capacitance electrode includes a first conductive layer and a second conductive layer stacked on the first conductive layer, and the contact portion is configured of the second conductive layer and is provided so as to be in contact with a drain region of the semiconductor layer.
