An organic light-emitting device includes a first electrode; a second electrode; an organic layer between the first electrode and the second electrode, the organic layer including an emission layer, and an electron transport region between the emission layer and the second electrode. The emission layer includes a first compound represented by Formula 1 and a second compound represented by any one of Formulae 2-1 to 2-5. The electron transport region includes a third compound represented by Formula 7. The organic light-emitting device may have low driving voltage, high efficiency, and a long lifespan.
