Abstract: An electro-optical device includes one or more control lines that include a scanning line, a data line and a pixel circuit. The pixel circuit has a drive transistor, a write-in transistor with a gate which is electrically connected to the scanning line, a light-emitting element that emits light at a brightness that depends on the size of a current that is supplied through the drive transistor, and a control line which overlaps the gate of the drive transistor when viewed from a direction that is perpendicular to a surface of a substrate on which the pixel circuit is formed is included in the one or more control lines.

Abstract: A pixel circuit is disposed in correspondence to an intersection of a scanning line and a data line. The pixel circuit is provided with a wiring for shielding an relay electrode connected to a source of the transistor for controlling a current flowing to a light emitting element from the data line. The wiring has a structure in which an relay electrode located on the same layer as the data line, an relay electrode located on the same layer as the relay electrode, an electrode portion of a conductive layer between the data line and the relay electrode are electrically connected to each other.
