Display device, driving method for the display device, and electronic apparatus

A driving method for a display device including

• 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 electrode and a source electrode of the driving transistor and stores the video signal written by the writing transistor;
• and
• a power supply line that supplies power supply potential to the pixels, the power supply potential selectively taking first potential for supplying an electric current to the driving transistor and second potential for applying reverse bias to the electro-optic element,
• the method comprising the step of:
• setting time in which potential of the power supply line changes from the first potential to the second potential at a preparation stage of threshold correction processing longer than time in which the potential of the power supply line changes from the second potential to the first potential before the threshold correction processing, the threshold correction processing being processing for changing, relative to initialized potential obtained when gate voltage of the driving transistor is initialized with reference potential, source voltage to potential obtained by subtracting threshold voltage of the driving transistor from the initialized potential.
