Abstract
A display device includes a display panel including a pixel including a pixel circuit and a light emitting element, a plurality of scan lines connected to the pixel circuit, an emission control line connected to the pixel circuit, and a data line connected to the pixel circuit. The pixel circuit includes a first capacitor connected to a first node and a second node opposite to the first node, a first circuit portion that includes a first transistor connected between the data line and the first node and a second transistor connected between the first transistor and the first node, and a second circuit portion connected to the second node and the light emitting element. Before the light emitting element emits light, a reference voltage is provided to a third node between the first transistor and the second transistor.
