    摘要: An organic light-emitting device includes a first electrode; a second electrode facing the first electrode; and an organic layer disposed between the first electrode and the second electrode and including a first emission layer and a second emission layer; wherein the first emission layer is located closer to the first electrode than the second emission layer and includes a first hole transport host, a first electron transport host, and a first phosphorescent dopant, and, in the first emission layer, an amount of the first hole transport host is greater than an amount of the first electron transport host, the second emission layer includes a second hole transport host, a second electron transport host, and a second phosphorescent dopant, and, in the second emission layer, an amount of the second electron transport host is greater than an amount of the second hole transport host, and the first emission layer and the second emission layer are configured to emit light of substantially the same color.
