Abstract: A display device includes a pixel, a scan driver supplying first to third scan signals in a first non-emission period and supplying the second scan signal in a second non-emission period, an emission driver supplying an emission control signal in the first and second non-emission periods, and a data driver supplying a data signal in the first non-emission period. The pixel includes a light-emitting element, a first transistor, a second transistor connected between the data line and a second node, a first capacitor connected between the first and second nodes, a third transistor connected between a third power line and the first node, a storage capacitor connected between the first and third nodes, a fourth transistor connected between the third node and a fourth power line, a fifth transistor connected between the first power line and the first transistor, and a sixth transistor supplying a fifth supply voltage.
