Abstract:
An organic light emitting diode includes a first electrode layer, a first common layer disposed on the first electrode layer, 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 layer disposed on the second common layer. The organic light emitting layer and the first common layer have the same directional property. Since an injection/transportation of charge at an interface of the first common layer and the organic light emitting layer becomes smooth, charges are not accumulated at the interface. Thus, life of the organic light emitting diode is extended.
