Amine-based compound and organic light-emitting device including the same

摘要

An amine-based compound and an organic light-emitting diode including the amine-based compound are provided. The amine-based compound may be used between a pair of electrodes of an organic light-emitting diode. For example, the amine-based compound may be used in an emission layer and/or between the emission layer and an anode (for example, in a hole injection layer, a hole transport layer, a functional layer having a hole injection ability and a hole transport ability). Accordingly, an organic light-emitting diode including a first electrode, a second electrode facing the first electrode, and an organic layer that is interposed between the first electrode and the second electrode, and includes the amine-based compound is provided.
