  • Organic light emitting diode and method of manufacturing the same
    Patent number: 9196857
    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.
