Abstract:
Provided is a display device in which a pixel circuit is arranged, the pixel circuit including a P channel type driving transistor that drives a light emitting unit, a sampling transistor that samples a signal voltage, a light emission control transistor that controls light emission/non-light emission of the light emitting unit, a holding capacitor that is connected between a gate electrode and a source electrode of the driving transistor, and holds the signal voltage written by the sampling by the sampling transistor, and an auxiliary capacitor that is connected between the source electrode of the driving transistor and a node having fixed potential, the display device including: a current path that flows a current flowing in the driving transistor in a non-light emission period of the light emitting unit into a predetermined node.
