Lighting apparatus using organic light emitting diode

Abstract:

An organic light emitting diode comprises an anode; an organic layer disposed on the anode and including a plurality of phosphorescent light emitting layers; and a cathode disposed on the organic layer, wherein a phosphorescent light emitting layer having a highest degree of horizontal orientation of a dopant among the plurality of phosphorescent light emitting layers is disposed to be adjacent to the cathode, and wherein the anode includes a short reduction pattern which implements a narrow path.
