Abstract:
A heterocyclic compound represented by Formula 1 or Formula 2 below, and an organic light-emitting device including the heterocyclic compound. The organic light-emitting device may include an organic layer containing the heterocyclic compound, and thus may have a low driving voltage, a high-emission efficiency, and long lifespan characteristics. wherein R1 to R12, Ar1, Ar2, A, B, a, and b are defined as in the specification.
