    摘要： Disclosed is a pixel circuit and a display device including the pixel circuit. The pixel circuit includes a driving element connected to a first node, a second node, and a third node; a first capacitor connected between the second node and a fourth node; a second capacitor connected between the third node and the fourth node; a light emitting element; a first switch element supplying an initialization voltage to the fourth node; a second switch element supplying the initialization voltage to the second node; a third switch element supplying a data voltage to the second node; and a fourth switch element supplying a reference voltage to the third node or to a fifth node connected to an anode electrode of the light emitting element.
