Abstract:
Disclosed is a method of fabricating an organic light emitting device and an organic light emitting device fabricated using the same. The method comprises the steps of sequentially forming a cathode made of metal, at least one organic material layer including a light emitting layer and an anode on a substrate, and additionally comprises the step of forming a thin metal film on a native oxide layer that is spontaneously formed on the cathode before forming of the organic material layer.
