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 comprising an anthracene-based host substituted with at least one deuterium and a boron-based dopant, at least one electron blocking layer comprising an aryl-substituted amine-based compound, and optionally at least one hole blocking layer comprising at least one of an azine-based compound and a benzimidazole-based compound. The organic light emitting diode and the organic light emitting device has improved luminous efficiency and enhanced luminous lifespan.
