Abstract: An organic light-emitting device includes: a first electrode; a second electrode; and an organic layer disposed between the first electrode and the second electrode, the organic layer having a first emission layer, a second emission layer disposed between the first emission layer and the second electrode, and at least one auxiliary layer, having a first host or a second host, the first emission layer may include a first host, a second host, and a first dopant; and the second emission layer may include a first host, a second host, and a second dopant; wherein the first host is a hole transport host, and the second host may include at least one of an electron transport host and a bipolar host; the first dopant and the second dopant, each may include, independently from one another, at least one of a phosphorescent organometallic compound and a thermally activated delayed fluorescence (“TADF”) compound satisfying Equation 1 as defined herein.
