The present disclosure relates to organic compounds and an organic light emitting display device using the same and more particularly, to an organic light emitting display in which an organic compound represented by the following Chemical Formula 1 is used for a hole transport layer or an electron blocking layer of the organic light emitting element to easily transport holes injected from an anode to a light emitting layer and suppress the leakage of electrons from the light emitting layer. Therefore, it is possible to provide an organic light emitting display device with high luminous efficiency and long lifetime.

Organic compounds and organic light emitting display device using the same

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.

Organic electroluminescent device

Disclosed is a novel compound and an organic light-emitting device. The novel compound is represented by the following Chemical Formula 1, and when the novel compound is used as a material for a hole transport layer of an organic light emitting device, the novel compound allows the device to have lowered drive voltage, and improved efficiency and lifespan characteristics.
