Abstract: Provided are an organic light emitting diode and a method of manufacturing the same. The organic light emitting diode adjusts an optical resonance thickness and prevents spectrum distortions without use of an auxiliary layer. The organic light emitting diode includes a first electrode that is optically reflective; a second electrode that is optically transmissible and faces the first electrode; an organic emission layer interposed between the first electrode and the second electrode, the organic emission layer including: a first emission layer including a mixed layer that contains a host material and a dopant material, and a second emission layer comprising only the host material; and a carrier injection transport layer interposed between the organic emission layer and the first electrode or between the organic emission layer and the second electrode.

Abstract: Provided are an organic light emitting diode and a method of fabricating the same, which can reduce the efficiency of electron injection and transport at low brightness to cause low luminous efficiency, thus preventing the organic light emitting diode from emitting light when displaying black. The organic light emitting diode includes a first electrode, an emission layer disposed on the first electrode, a second electrode disposed on the emission layer, and a metal layer formed of a metal element to a thickness of 5 to less than 50 ?. The metal layer is disposed between the first electrode and the emission layer or between the emission layer and the second electrode.
