Abstract: A pixel circuit and a display device including the same are disclosed. The pixel circuit includes a driving element including a first electrode connected to a first node to which a pixel driving voltage is applied, a gate electrode connected to a second node, and a second electrode connected to a third node, and configured to supply an electric current to a light emitting element; a first switch element discharging the second node; and a second switch element configured to supply a data voltage to the second node. The light emitting element and the first switch element are commonly connected to a VSS node to which a low-potential power supply voltage is applied.
