摘要： Provided is a tribenzazole amine derivative represented by Formula 1 that effectively absorbs high energy UV light from an external light source to minimize damage to organic materials present in an organic electroluminescent device, contributing to a substantial improvement in the lifetime of the organic electroluminescent device. Also provided is an organic electroluminescent device using the tribenzazole amine derivative. The organic electroluminescent device includes a first electrode, a second electrode, and an organic layer arranged between the first and second electrodes. The organic layer includes the tribenzazole amine derivative.
