ABSTRACT:
An organic light emitting diode element and an EL drive transistor are arranged in each of a plurality of pixel areas defined by two adjacent scanning signal wirings and neighboring video signal wiring and current supply wiring. A current supplied to the organic light emitting diode element connected to a drain area of the drive transistor is controlled by a voltage between a gate electrode and a source electrode of the EL drive transistor, and a body electrode provided to the EL drive transistor as a fourth electrode is earthed in such a manner that excessive carriers generated in a channel area are caused to escape from the drive transistor through the body electrode.
