Abstract
A display device can include a light emitting element, and a pixel driving circuit connected to the light emitting element and configured to include first to fourth nodes. The pixel driving circuit can include a driving transistor connected to the first to third nodes, a plurality of switching transistors, and a storage capacitor. Among the plurality of switching transistors, the switching transistor connected to a source node of the driving transistor is controlled by a second scan signal, and is configured to apply a data voltage to the source node of the driving transistor. The second scan signal can be applied one or more times during one frame.
