Summary:A disclosed display device is equipped with a pixel array unit (30) obtained by forming a matrix arrangement of pixel circuits containing: a light-emitting unit (21); a write transistor (23) for writing the signal voltage (Vsig) of a video signal; a storage capacitor (24) for storing the signal voltage (Vsig) written by the write transistor (23); a drive transistor (22) for driving the light-emitting unit (21) on the basis of the signal voltage (Vsig) stored by the storage capacitor (24); and an auxiliary capacitor (25) having one end thereof connected to a source node of the drive transistor (22). The disclosed display device is further equipped with a control unit (90) for, after threshold correction processing, setting the operation point of the drive transistor (22) as a cut-off region by applying a potential change to a source electrode of the drive transistor (22) by coupling via the auxiliary capacitor (25). 根据本公开的显示装置配置有：通过形成像素电路的矩阵布置而获得的像素阵列单元(30)，包括：发光单元(21)、写入视频信号的信号电压(Vsig)的写入晶体管(23)、保持由写入晶体管(23)写
