Abstract

The present disclosure relates to an organic light emitting device. In particular, the present disclosure relates to an organic light emitting diode and an organic light emitting device each of which includes at least one emitting material layer including a boron-based dopant and an anthracene-based host substituted with at least one deuterium, at least one electron blocking layer including an amine-based compound substituted with at least one polycyclic aryl, and optionally at least one hole blocking layer including an azine-based or a benzimidazole-based compound. The organic light emitting diode and the organic light emitting device has improved luminous efficiency and enhanced luminous lifespan.
