Beschreibung
Zusammenfassung:	An organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; an emission region between the first electrode and the second electrode and including a first emission layer and a second emission layer; and a hole blocking layer between the first emission layer and the first electrode, or between the second emission layer and the second electrode, wherein the second emission layer may be between the first emission layer and the hole blocking layer, the first emission layer may include a first host and a first light-emitting material, the second emission layer may include a second host and a second light-emitting material, and the first light-emitting material and the second light-emitting material may respectively be included in the first emission layer and the second emission layer at an identical ratio.
