Abstract
A display device includes a pixel array unit in which pixels are arranged, each pixel including a light emitting unit, a writing transistor that writes a video signal, a driving transistor that drives the light emitting unit based on the video signal written by the writing transistor, and a switching transistor that applies a fixed potential to one terminal of the light emitting unit, and a driving unit that causes the light emitting unit to enter a light extinction state by writing a voltage causing the driving transistor to enter a non-conduction state to a gate electrode of the driving transistor.
