Abstract
A 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; a light emitting element including an anode electrode connected to the third node, and a cathode electrode connected to a power line; a first switch element to supply a data voltage of pixel data to the second node; a second switch element to supply an initialization voltage to the second node; a third switch element to supply a reference voltage to the third node; a fourth switch element configured to connect the third node to a power line to reset a voltage of the anode electrode of the light emitting element to the pixel reference voltage; and a capacitor between the second and third node.
