Abstract: The present invention provides a novel compound of an amine derivative including a spiro compound. The novel compound has excellent hole transport characteristics. Thus, when the novel compound is applied to a hole transport layer, an auxiliary hole transport layer and an electron blocking layer of an organic light-emitting device, the device realizes low driving voltage, high efficiency, high thermal stability and long life-span. Further, when the novel compound is applied as a blue light-emitting material, the device realizes a low driving voltage and high efficiency.
