发明名称 Electro-optical device and electronic apparatus
摘要 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.
