An organic light-emitting device includes an emission layer including a first compound represented by Formula 1, a second compound, and a third compound. The first compound may be an organometallic compound that acts as a phosphorescent dopant, and the second and third compounds may form an exciplex. The device may have a low driving voltage, high luminance, high efficiency, and a long lifespan:
