Abstract: A pixel includes: an organic light emitting diode; a first transistor having a second electrode connected with an anode electrode of the organic light emitting diode and controlling the amount of current supplied to the organic light emitting diode; a second transistor connected between a data line and a second node and turned on when a scan signal is supplied to a scan line; a third transistor connected between a gate electrode and a second electrode of the first transistor and having a turn-on time partially overlapping the turn-on time of the second transistor; a fifth transistor connected between the second node and a power line receiving first power and having a turn-on time not overlapping the turn-on time of the second transistor; and a storage capacitor connected between a gate electrode of the first transistor and the second node.
