Abstract
An organic light-emitting device including a first electrode, a second electrode facing the first electrode, and an emission layer disposed between the first electrode and the second electrode, wherein the emission layer includes a first material not including an electron transport moiety, a second material including at least one electron transport moiety, a third material having reorganization energy of about 0.4 eV or more, and a light-emitting material, wherein the first material, the second material, the third material, and the light-emitting material are different from one another, and wherein a ratio of a light-emitting component emitted from the light-emitting material to a total of light-emitting components emitted from the emission layer is about 90% or more.
