Abstract:
1. An electro-optical device comprising: a scanning line and a data line that intersect one another; and a pixel circuit that is disposed in correspondence to an intersection of the scanning line and the data line, the pixel circuit including a driving transistor supplying a current according to a voltage between a gate and a source to the source from a drain, a switching transistor electrically connected between the gate of the driving transistor and the data line, a first capacitor holding a voltage between the gate and the source of the driving transistor, a light emitting element having an anode which is connected to the source of the driving transistor, and emitting light according to the current flowing from the anode to a cathode, and a second capacitor having one end connected to the source of the driving transistor and the other end connected to a feed line, a first relay electrode that is overlapped with a portion of a gate electrode forming the gate of the driving transistor, and electrically connected to the source of the driving transistor when seen in plan view, and the feed line being made of a wiring layer between a wiring layer forming the gate of the driving transistor and a wiring layer forming the data line, and having an electrode portion located between the data line and the gate of the driving transistor when seen in plan view, an electrode portion of the feed line being overlapped with a portion of the first relay electrode when seen in plan view, the first capacitor interposing a first interlayer dielectric film between the gate electrode and the first relay electrode, and the second capacitor interposing a second interlayer dielectric film between the first relay electrode and the electrode portion of the feed line.
