1. An organic light-emitting device comprising:
a first electrode;
a second electrode; and
an organic layer between the first electrode and the second electrode,
wherein the organic layer comprises an emission layer,
the emission layer comprises a first compound, a second compound, a third compound, and a fourth compound,
the first compound is a first hole transporting compound,
the second compound is a first electron transporting compound,
the third compound is a second hole transporting compound or a second electron transporting compound,
the fourth compound is a dopant compound,
the first compound and the second compound form a first exciplex,
the first compound and the third compound, or the second compound and the third compound, form a second exciplex,
the first exciplex and the second exciplex are different from each other, and
the emission layer is to emit phosphorescence or delayed fluorescence.
