A pixel capable for compensating for the degradation of an organic light emitting diode. The pixel includes an organic light emitting diode; a pixel circuit including a driving transistor for controlling an electric current capacity flowing from a first power source to a second power source via the organic light emitting diode; and a compensation unit for controlling a voltage of a gate electrode of the driving transistor to correspond to a degradation of the organic light emitting diode. The compensation unit includes first and second feedback capacitors coupled in series between an anode electrode of the organic light emitting diode and the gate electrode of the driving transistor and a switching transistor coupled between a common node of the first and second feedback capacitors and a reset power source and for turning on when a control signal is supplied to a control line coupled to the switching electrode.
