Abstract
A pixel circuit according to an embodiment and a display device including the same are disclosed. The pixel circuit includes a driving element including a driving element including a first electrode connected to a pixel driving voltage line, a gate electrode connected to a first node, and a second electrode connected to a second node, a first switch element configured to supply a data voltage to the first node in response to a first gate signal, a second switch element configured to supply an initialization voltage to the first node in response to a second gate signal, a third switch element configured to supply a reference voltage to a third node in response to a third gate signal, a fourth switch element configured to connect the second node and the third node in response to a fourth gate signal, a first capacitor connected between the first node and the second node, a second capacitor connected between the pixel driving voltage line and the second node, a third capacitor connected between a gate electrode of the second switch element and the second node and a light-emitting element connected between the third node and a low-potential power voltage line.
