Abstract:
A display device can include a light emitting element and a pixel circuit including a driving transistor; a first capacitor connected between the driving transistor and a first node; a first transistor connected between the first capacitor and a data line to operate based on a first scan signal; a first light emission transistor connected between the first capacitor and a reference voltage line to operate based on a light emission signal; and a second light emission transistor connected between the driving transistor and a low-potential voltage line to operate based on the light emission signal. The first scan signal sequentially includes a dummy scan signal section and driving scan signal section for turning on the first transistor, and the light emission signal includes a coupling period for turning on the first and second light emission transistors between the dummy scan signal section and the driving scan signal section.
