Patent ID: 8823692

Claim:
A display device comprising: a pixel array unit in which pixels are arranged in a matrix shape, each of the pixels including an electro-optic element, a writing transistor that writes a video signal, a driving transistor that drives the electro-optic element according to the video signal written by the writing transistor, and a storage capacitor that is connected between a gate terminal and a first current terminal of the driving transistor and stores the video signal written by the writing transistor; and a power supply line configured to supply a power supply potential to the second current terminal of the driving transistor, the power supply potential selectively taking a first potential for supplying an electric current to the driving transistor and a second potential for applying reverse bias to the electro-optic element, wherein a first time period of the power supply potential changing from the first potential to the second potential precedes a second time period of the power supply potential changing from the second potential to the first potential, the first time period is longer than the second time period, and the first time period and the second time period occur at a preparation stage of threshold correction processing before the threshold correction processing, the threshold correction processing being processing for changing, relative to an initialized potential obtained when a gate voltage of the driving transistor is initialized with a reference potential, a source voltage of the driving transistor to a potential obtained by subtracting a threshold voltage of the driving transistor from the initialized potential, wherein the gate voltage is lower than the source voltage throughout the preparation stage of threshold correction processing.
