Original Abstract Submitted
Embodiments provide a light-emitting device that include a first electrode, a second electrode facing the first electrode, and an interlayer between the first electrode and the second electrode. The interlayer includes an emission layer, and the emission layer includes a first emission layer and a second emission layer. The first emission layer includes a first host and a first-first dopant, or a first host, a first-first dopant, and a first-second dopant. The second emission layer includes a second host and a second-first dopant, or a second host, a second-first dopant, and a second-second dopant. The emission layer includes the first-second dopant and/or the second-second dopant, the first emission layer and the second emission layer directly contact each other, and a thickness of the second emission layer is greater than a thickness of the first emission layer.
