    摘要： An organic light-emitting device includes: a first electrode; a second electrode; and an organic layer between the first electrode and the second electrode, wherein the organic layer includes an emission layer having a first layer, and the first layer includes a first compound, a second compound, and a third compound. The first compound is a hole transporting host compound, the second compound is an electron transporting host compound, and the third compound is a hole transporting host compound or an electron transporting host compound. The first compound and the second compound form a first exciplex, and the first compound and the third compound, or the second compound and the third compound form a second exciplex, where the first exciplex and the second exciplex are different from each other.
