Claim Text:
1. An electro-optical device in which a scan line, a data line, and a pixel circuit are formed on a semiconductor substrate, wherein the pixel circuit includes a light emitting element having a first electrode and a second electrode, a driving transistor that controls a current in accordance with a potential of a gate node while being electrically connected to the first electrode of the light emitting element during a period when the current is supplied to the light emitting element, and a switching transistor that is an N-channel transistor and is electrically connected between the gate node of the driving transistor and the data line, wherein a first substrate potential is supplied to the switching transistor and is lower than a minimum value of a source potential of the switching transistor, and wherein a second substrate potential, different from the first substrate potential, is supplied to the driving transistor.
