Patent ID: 8916859

Claim:
A pixel comprising: an organic light emitting diode disposed in a light emitting area; a transistor disposed in a non-light emitting area adjacent to the light emitting area to control a driving current flowing through the organic light emitting diode; and a common line disposed in the non-light emitting area and applied with a reference voltage to prevent the organic light emitting diode from generating a light by a leakage current in the transistor, the organic light emitting diode comprising: a first electrode connected to the transistor to receive a first voltage; a first common layer disposed on the first electrode; an organic light emitting layer disposed on the first common layer; a second common layer disposed on the organic light emitting layer; and a second electrode disposed on the second common layer to receive a second voltage having a different voltage level from the first voltage, the common line being disposed between the first common layer and the second common layer and making electrical contact with the first common layer.
