Abstract
A pixel circuit and a display device including the same are disclosed. The pixel circuit includes a driving element connected to a first node, a second node, and a third node; a capacitor connected between the second node and the third node; a first switch element connected between a data line to which a data voltage of pixel data is applied and the second node; a second switch element connected between the first node and the second node; a third switch element; a fourth switch element; and a light emitting element. When the third switch element is turned on, a reference voltage is applied to the third node or an anode electrode of the light emitting element.
