Abstract
A display device according to the present disclosure includes: a pixel array unit () in which pixel circuits (A) are disposed in a matrix form, the pixel circuits each including a light emission unit (), a write transistor () that writes a signal voltage (Vsig) of a video signal, a retention capacitor () that retains the signal voltage (Vsig) written by the write transistor (), a drive transistor () that drives the light emission unit () on the basis of the signal voltage (Vsig) retained by the retention capacitor (), and an auxiliary capacitor () of which one terminal is connected to a source node of the drive transistor (); and a control unit () that provides a potential change to a source electrode of the drive transistor () by coupling through the auxiliary capacitor () to set an operation point of the drive transistor () as a cut-off region after the threshold value correction process.
