Abstract
A display device includes a pixel circuit connected to a light emitting element. The pixel circuit includes a driving transistor having a gate electrode, a source electrode, and a drain electrode, and a capacitor connected with the gate electrode. The pixel circuit is driven according to a first period when a reference voltage is applied to the gate electrode, a second period when a gate-source voltage difference of the driving transistor is a threshold voltage of the driving transistor, a third period when the reference voltage is applied to the capacitor, and a voltage of the gate electrode varies due to a coupling phenomenon of the capacitor, a fourth period when a high-potential voltage higher than the reference voltage is applied to the source electrode, and a fifth period when the driving transistor is turned on to cause the light emitting element to emit light.
