Abstract
In an element substrate of an electro-optical device, a data line on a first metal layer with light shielding properties overlaps a semiconductor layer in a planar view, and a relay electrode on the first metal layer with light shielding properties has an end on the first wire side which extends along the semiconductor layer in the Y direction (first direction) and faces the data line through a first gap. A second metal layer with light shielding properties is formed between the first metal layer and a layer of a pixel electrode, and a first shielding section, which overlaps the first gap in a planar view by a first projection section of a constant potential line, is configured on the second metal layer. Both the first metal layer and the second metal layer include an aluminum layer, have a small electrical resistance and a substantially infinite OD value.
