Claim:
1. A pixel, comprising: a switching transistor to be turned on by a scan signal and to transmit a data voltage according to an applied image data signal through a data line, a storage capacitor to store the data voltage, and first and second pixel areas commonly connected to the switching transistor and the storage capacitor to emit light with a driving current according to the data voltage, each of the first and second pixel areas including: an organic light emitting diode to emit light, a first transistor to generate and transmit a driving current according to the data voltage through a path that reaches a second power source from a first power source via the organic light emitting diode, a second transistor to diode-connect a gate electrode and a drain electrode of the first transistor, and a compensation capacitor connected between the gate electrode of the first transistor and the switching transistor, the compensation capacitor to maintain a voltage corresponding to a threshold voltage of the first transistor for a predetermined period.
