Abstract
A liquid crystal device serves as an electro-optical device and includes, on a base member of an element substrate, a first shield layer disposed between a gate electrode and a drain electrode of a TFT, and a second shield layer provided between the drain electrode and a data line serving as a signal line. A first holding capacitor is configured by part of the drain electrode, the first dielectric layer, and the second shield layer.
