Abstract

Embodiments of the present invention are directed to heteroarylamine compounds and organic light-emitting devices including the heteroarylamine compounds. The organic light-emitting devices using the heteroarylamine compounds have high-efficiency, low driving voltages, high luminance and long lifespans.
