Abstract: The present disclosure relates to a novel organic compound and an organic electroluminescent device including the same. More specifically, the present disclosure relates to a deuterated organic compound and an organic electroluminescent device including at least one organic layer made of the deuterated organic compound. Thus, the organic electroluminescent device exhibits a longer lifetime, lower voltage implementation, and improved luminous efficiency.

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.
