Patent ID: 7777710

Claim:
A display device comprising: a power supply line; a first scan line driver circuit electrically connected to one end of a first scan line; a second scan line driver circuit electrically connected to one end of a second scan line; a current supply line; a light-emitting element; a scan line auxiliary circuit electrically connected to the other end of the first scan line, the scan line auxiliary circuit including at least one switching element; a driving transistor electrically connected in series between the current supply line and the light-emitting element; a storage capacitor, one electrode of which is electrically connected to a gate electrode of the driving transistor, and the other electrode of which is electrically connected to the current supply line; a reset transistor, a gate electrode of which is electrically connected to the first scan line, and one of a source electrode and a drain electrode of which is electrically connected to the current supply line; a switch transistor having a gate electrode electrically connected to the second scan line, the switch transistor being electrically connected between the other of the source electrode and the drain electrode of the reset transistor and one electrode of the storage capacitor; and a selection transistor having a gate electrode electrically connected to a data line, the selection transistor being electrically connected in series between the switch transistor and the first scan line, wherein the first scan line is configured to being electrically connected to the power supply line through the switching element, and a gate potential of the driving transistor is set equal to a potential of the power supply line, by controlling the switching element with a signal potential of the first scan line and a signal potential of the second scan line which is supplied from the second scan line driver circuit.
