Abstract
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.
