摘要： Provided is a tertiary amine derivative. The tertiary amine derivative effectively absorbs light in the UV region from high-energy external light sources to minimize damage to organic materials in organic electroluminescent devices, contributing to a substantial improvement in the lifetime of the organic electroluminescent devices. An organic electroluminescent device includes a first electrode, a second electrode, an organic layer arranged between the first and second electrodes, and a capping layer wherein the capping layer includes the tertiary amine derivative of Formula 1:
