Abstract: Disclosed is an organic electroluminescent device. More specifically, disclosed is an organic electroluminescent device comprising at least one organic layer comprising at least two dopant compounds therein. The electroluminescent device employs both of a boron-based dopant and a pyrene-based dopant to provide improved color characteristics, efficiency and lifespan.
