| description | Disclosed are a pixel circuit, and a pixel driving method and a display device using the same. The pixel circuit comprises: a driving element including a first electrode connected to a first node, a first gate electrode connected to a second node, a second electrode connected to a third node, and a second gate electrode to which a preset voltage is applied; a light emitting element including an anode electrode connected to a fourth node and a cathode electrode with a low-potential power voltage applied, and driven in accordance with a current from the driving element; a first switch element connected to the part between the first node and the second node; and a second switch element connected to the part between the third node and the fourth node. Therefore, element reliability can be secured.
