Patent ID: 8345031

Claim:
A display device comprising: a pixel array unit in which pixels are arranged in a matrix, the pixels each including an electrooptical element, a writing transistor for writing an image signal, a storage capacitor for storing the image signal written by the writing transistor, and a driving transistor for driving the electrooptical element in accordance with the image signal stored in the storage capacitor, the pixels each having a function of performing a threshold correction process for, prior to driving the electrooptical element to emit light, changing a potential of a source of the driving transistor to a potential obtained by subtracting a threshold voltage of the driving transistor from an initial potential of a gate of the driving transistor; and a power supply unit configured to set, as a power supply potential of a power supply line for supplying a current to the driving transistor, different potential values for a threshold correction period during which the threshold correction process is performed and for a light-emission period during which the electrooptical element emits light, wherein the power supply unit sets the power supply potential for the threshold correction period, relative to the power supply potential for the light-emission period, to a potential at which a drain-source voltage of the driving transistor after performance of the threshold correction process is made the same as a drain-source voltage of the driving transistor during light emission of the electrooptical element.
