Abstract
In an electro-optical device, a first light shielding wall and a second light shielding wall electrically couple a gate electrode and a scan line inside a first groove and a second groove that pass through a side of a semiconductor film of a transistor and reach a scan line on a lower layer side. A first protruding portion and a second protruding portion for contact with an upper layer side are provided at the semiconductor film. Of the first light shielding wall and the second light shielding wall, the second light shielding wall located on an opposite side to a projection direction of the first protruding portion extends to at least a side of the first protruding portion, and the first light shielding wall located on an opposite side to a projection direction of the second protruding portion extends to at least a side of the second protruding portion.
