Abstract:
A display device includes a pixel array unit formed by disposing pixel circuits having a P-channel type drive transistor that drives a light-emitting unit, a sampling transistor that applies a signal voltage, a light emission control transistor that controls emission/non-emission of the light-emitting unit, a storage capacitor that is connected between a gate electrode and a source electrode of the drive transistor and an auxiliary capacitor that is connected to the source electrode, and a drive unit that, during threshold correction, respectively applies a first voltage and a second voltage to the source electrode of the drive transistor and the gate electrode thereof, the difference between the first voltage and the second voltage being less than a threshold voltage of the drive transistor, and subsequently performs driving that applies a standard voltage used in threshold correction to the gate electrode when the source electrode is in a floating state.
