Patent ID: 6963173

Claim:
A light emission type display apparatus comprising: a substrate having an electrical insulative surface; a plurality of scanning signal wirings provided on the surface of the substrate; a plurality of video signal wirings provided on the surface of the substrate so as to cross the scanning signal wirings; a plurality of current supply wirings provided on the surface of the substrate so as to cross the scanning signal wirings; light emitting elements each of which is arranged in each of a plurality of pixel areas defined by the two adjacent scanning signal wirings and neighboring video signal wiring and current supply wiring; and drive transistors which drive the light emitting elements, each of the drive transistors having a channel area, a gate electrode, a drain electrode provided on a drain area, a source electrode provided on a source area, and a body electrode, said channel area, said drain area, and said source area formed on a single crystal silicon film provided on one side of a respective drive transistor, a current supplied to the light emitting element connected to the drain area of the drive transistor being controlled by a voltage between the gate electrode and the source electrode of the drive transistor, and the body electrode of the drive transistor being earthed in such a manner that excessive carriers generated in the channel area are caused to escape from the drive transistor through the body electrode.
