Abstract

An organic light-emitting device includes a first electrode; a second electrode facing the first electrode; an emission layer between the first electrode and the second electrode; a hole transport region between the first electrode and the emission layer; and an electron transport region between the emission layer and the second electrode, wherein the emission layer includes a first material represented by Formula 1 and a second material represented by any one of Formulae 2-1 to 2-5, and the hole transport region includes a third material represented by Formula 3. The organic light-emitting device may have high efficiency and a long lifespan.
