Abstract
An electro-optical device includes a base material as a substrate, a TFT as a transistor, a scanning line as a light shielding layer between the base material and the TFT, and a holding capacitor between the base material and the scanning line. The holding capacitor includes a first conductive layer, a second conductive layer provided on the first conductive layer via a first capacitor insulating layer, a third conductive layer electrically connected to the second conductive layer via a first contact hole provided in an insulating layer covering the second conductive layer, and a fourth conductive layer provided on the third conductive layer via a second capacitor insulating layer.
