Electro-optical device and electronic apparatus
An electro-optical device includes a reflective layer, a light emitting element including a light emitting layer formed between an anode and a cathode, and a driving transistor configured to control a current flowing through the light emitting element. In the same layer as the reflective layer, a relay electrode included in a current path from the driving transistor to the anode is formed with a gap between the relay electrode and the reflective layer. A contact electrode electrically connecting the relay electrode and the anode is formed as a light shielding layer that blocks light entering the gap.
