Abstract: Embodiments of the present disclosure are related to a display device, a turn-on state, a turn-off state of a driving transistor can be easily controlled by a control of a control voltage applied to a control gate electrode opposed to a driving gate electrode of the driving transistor and a non-light-emitting driving can be performed in a display driving. Furthermore, as the non-light-emitting driving is performed by the control voltage applied to the control gate electrode of the driving transistor, the non-light-emitting driving can be performed independently from a period in which a scan signal is applied, the non-light-emitting driving can be performed without affecting a display driving and a video response time of the display device can be improved.
