Abstract
Official abstract text for this publication.
A pixel of an organic light emitting display device includes a transistor configured to output a first source voltage, an organic light emitting diode coupled to the transistor, and a wiring configured to be applied with a reference voltage to ground a leakage current of the transistor. The organic light emitting diode includes a first electrode configured to receive the first source voltage, a first common layer on the first electrode, an organic light emitting layer on the first common layer, and a second electrode on the organic light emitting layer and configured to be applied with a second source voltage different from the first source voltage. The first common layer is coupled to the wiring.
