Abstract
An organic compound including a carbazolyl moiety having a p-type property, a dibenzofuranyl or dibenzothiophenyl moiety having an n-type property and further substituted with a dibenzofuranyl or dibenzothiophenyl moiety is disclosed. An organic light emitting diode and an organic light emitting device including the organic compound are also disclosed. The organic compound has excellent thermal resistance and a high energy level due to the combination of fused hetero aromatic rings. Therefore, the organic light emitting diode and the organic light emitting device including the organic compound show excellent luminous efficiency and an improved luminous lifetime.
