摘要： An organic light-emitting device includes, in the following order, a first electrode, a first light-emitting layer, a charge generation layer, a second light-emitting layer, and a second electrode. The first light-emitting layer contains a first light-emitting material. The second light-emitting layer contains a second light-emitting material. Each of the first light-emitting material and the second light-emitting material emits light of a first color. The first light-emitting material and the second light-emitting material are different.
