Abstract
Provided are a monoamine derivative represented by the following Formula 1, and an organic electroluminescent device including the same. When the monoamine derivative represented by Formula 1 is used as a hole transport or hole injection material in the device, the operating voltage may be lowered and the emission efficiency may be improved.
Claims2
