摘要：
An organic light emitting device and a method of manufacturing the same, the organic light emitting device includes a first electrode, a second electrode, and an organic layer that has at least a multi-coated emissive layer and which is interposed between the first and second electrodes. The multi-coated emissive layer is a single layer composed of a neutral emissive material and an no−ne parameter of the emissive layer is greater than an no−ne parameter of a single-coated layer. The organic light emitting device has a longer lifetime and high efficiency.
