Abstract: The present disclosure relates to a pixel circuit and a display device using the same. The pixel circuit includes a first switch element configured to connect a first node to a third node in a sampling step, a second switch element configured to supply a data voltage to a second node in the sampling step, a third switch element configured to supply a pixel driving voltage to the second node in a emission step after the sampling step, a fourth switch element configured to connect the third node to an anode of a light-emitting element in the emission step, a first capacitor connected to the first node, a second capacitor connected between the third node and the anode of the light-emitting element, and a third capacitor connected between the anode and the cathode of the light-emitting element.
