Abstract
A display device includes a pixel array unit in which pixel circuits are disposed in a matrix form, the pixel circuits each including a light emission unit, a write transistor that writes a signal voltage of a video signal, a retention capacitor that retains the signal voltage written by the write transistor, and a drive transistor that drives the light emission unit on the basis of the signal voltage retained by the retention capacitor; and a common line that is wired along a pixel row, for each pixel row. The pixel circuit includes a switching transistor which selectively connects the common line and a source electrode of the drive transistor.
