Abstract

An organic light-emitting device includes a first electrode, a second electrode facing the first electrode, an organic layer between the first electrode and the second electrode and including an emission layer, and at least one of a first layer and a second layer, wherein the first layer is positioned in a path where light generated in the emission layer is transmitted to the outside through the first electrode and the second layer is positioned in a path where the light generated in the emission layer is transmitted to the outside through the second electrode. The first layer and the second layer each include a compound having a certain formula.
