Abstract
The present disclosure relates to an organic light emitting diode that includes at least one emitting material layer including an anthracene-based host and a boron-based dopant, at least one electron blocking layer including an amine-based compound substituted with at least one fused aromatic or hetero aromatic ring, and optionally at least one hole blocking layer including an azine-based compound or a benzimidazole-based compound. The organic light emitting diode has enhanced luminous efficiency as well as excellent luminous lifetime.
