협약과제
초록
An organic light emitting diode (OLED) device is provided. The OLED device includes: a substrate; an anode formed on the substrate; a first organic thin layer formed on the anode; an organic emission layer formed on the first organic thin layer; a second organic thin layer formed on the organic emission layer; and a cathode formed on the second organic thin layer, wherein the first and second organic thin layers are formed in a single layer or a multi-layer, and at least a part of the first or second organic thin layer is doped with or formed of an insulator. The OLED device provides excellent durability, long life-time, and increased luminous efficiency by balanced charge injection caused by doping or stacking the insulator into or on the organic thin layer.
