A pixel capable of stably compensating for the threshold voltage of a driving transistor is disclosed. In one aspect, the pixel includes an organic light emitting diode (OLED), a first transistor for controlling an amount of current supplied from a first power supply coupled to a second node to the OLED to correspond to a voltage applied to a third node, and a second transistor coupled between the second node and a first node and turned on when a control signal is supplied to a control line. The pixel also includes a third transistor coupled between the third node and a reference power supply and turned on when the control signal is supplied, a first capacitor coupled between the first node and the first power supply, and a second capacitor coupled between the first node and the third node.
