Abstract: A pixel circuit is disclosed. The pixel circuit includes: a driving element including a first electrode connected to a first node, a gate electrode connected to a second node, and a second electrode connected to a third node; a light emitting element including an anode electrode connected to a fourth node and configured to be driven according to the current from the driving element; a first switch element configured to supply a data voltage to the second node; a second switch element configured to supply an initialization voltage to the first node; a third switch element configured to supply a reference voltage to the third node or the fourth node; a fourth switch element configured to supply a cathode voltage or the reference voltage to the third node or the fourth node; and a fifth switch element configured to supply a pixel driving voltage to the first node.
