Abstract:
An organic light-emitting device according to an embodiment of the present disclosure includes a first electrode, a second electrode opposite to the first electrode, a first light-emitter on the first electrode to emit first light of a first wavelength range, a second light-emitter between the first light-emitter and the second electrode, to emit second light of a second wavelength range, and a charge generation layer which includes a metal compound having a perovskite structure, is between the first light-emitter and the second light-emitter, and is to generate charges to provide to each of the first light-emitter and the second light-emitter.
