A heterocyclic compound represented by Formula 1A below and an organic light-emitting diode including the same: at least one of R1 to R7 is a group represented by Formula 1B below. in Formulae 1A and 1B, R1 to R9, Ar1, Ar2, A, B, a and b are the same as described in the detailed description section of the present application. The organic light-emitting diode including an organic layer including the heterocyclic compound has a low driving voltage, high luminescence efficiency, and a long lifetime.
