Abstract

A condensed cyclic compound represented by Formula 1:

Also disclosed is an organic light-emitting device including a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode, the organic layer including an emission layer and the condensed cyclic compound of Formula 1. An organic light-emitting device including the condensed cyclic compound of Formula 1 may have low driving voltage, high efficiency, a high luminance, and long lifetime.
