Patent ID: 7176989

Claim:
An electro-optical device comprising, above a substrate: a data line extending in a first direction; a scanning line extending in a second direction which intersects the data line; a pixel electrode and thin film transistor provided so as to correspond to an intersection region of the data line and the scanning line; a storage capacitor electrically connected to the thin film transistor and the pixel electrode, dielectric films which constitute the storage capacitor being made of at least two layers including different materials and one of the at least two layers being made of a material having a higher dielectric constant than that of the other layer; a relay layer that electrically connects the pixel electrode and the storage capacitor and that at least partially covers the storage capacitor to shade the storage capacitor from incident light; and a light shielding layer provided between the data line and the pixel electrode, the light shielding layer being formed along the data line and having a width wider than the width of the data line, the light shielding layer being formed to cover the entire data line in plan view, the light shielding layer at least partially covering the storage capacitor.
