Abstract: There are provided an organic light emitting diode and a method of manufacturing the same. The organic light emitting diode includes: an anode formed on a substrate; a protective layer having at least one inorganic material layer stacked therein, the at least one inorganic material layer containing at least one of a nano-clay and a graphite oxide; a light emitting polymer layer formed on the protective layer; and a cathode formed on the light emitting polymer layer. In the case of the organic light emitting diode, the injection concentration of holes may be controlled, such that the stability of an element may be improved and the lifespan thereof may be increased.
