Abstract: The present disclosure relates to a pixel circuit and a display device including the same. The pixel circuit includes: a first voltage node; a second voltage node; a driving element including a first electrode to which a pixel driving voltage is applied, a gate electrode connected to a first node, and a second electrode connected to a second node; a light emitting element including an anode electrode and a cathode electrode and configured to be driven by a current from the driving element, a capacitor connected between the first node and the second node; a first switch element connected between a data line to which a data voltage is applied and the first node and turned on in response to a first gate signal; and a second switch element connected between the second node and the second voltage node and turned on in response to a second gate signal.
