| 摘要 |
An organic electroluminescent device comprising: ```a substrate; ```a first electrode disposed over the substrate for injecting charge of a first polarity into an organic light emitting layer; ```a second electrode disposed over the first electrode for injecting charge of a second polarity opposite to said first polarity into an light emitting layer; ```an organic light emitting layer disposed between the first and the second electrode forming a pixel array having a pixel pitch P; and ```an encapsulant disposed over the second electrode, wherein the second electrode is transparent to light emitted by the organic light emitting layer and an optical structure is provided in the encapsulant, said second electrode and said encapsulant being of a thickness whereby the optical structure is a distance D from the light emitting layer, the distance D being less than half the pixel pitch P. A method of manufacturing such a device is also disclosed. |
