A heterocyclic compound is represented by Formula 1. n nAn organic light emitting device includes a first electrode, a second electrode and an organic layer between the first and second electrodes. The organic layer includes the heterocyclic compound. An organic light-emitting display apparatus includes the organic light-emitting device and a transistor including a source, a drain, a gate and an active layer. The source or the drain is electrically connected to the first electrode of the organic light-emitting device. |
