Abstract
An active type of light emission drive circuit includes a switching element which turns on in response to a scan pulse to allow a data signal to pass therethrough, a capacitive element for holding the data signal passed through the switching element during the ON state of the switching element, and a drive element for supplying a forward drive current to an organic EL element in accordance with the data signal held on the capacitive element to allow the organic EL element to emit light. The switching element is formed of a diode element that turns on by the potential difference between the scan pulse and the data signal when the scan pulse is supplied. A display device incorporating the drive circuit is disclosed.
