    摘要: Provided are a light-emitting device and an electronic apparatus including the light-emitting device. The light-emitting device may include: an emission layer between a first electrode and a second electrode. The emission layer may include i) a first emission layer and ii) a second emission layer between the first emission layer and the second electrode, the first emission layer may be in direct contact with the second emission layer, the first emission layer may include a first dopant, a first hole-transporting compound, and a first electron-transporting compound, the second emission layer may include a second dopant, a second hole-transporting compound, and a second electron-transporting compound, the first dopant may be identical to the second dopant, and the first electron-transporting compound may be different from the second electron-transporting compound, electron mobility of the second electron-transporting compound may be greater than electron mobility of the first electron-transporting compound.
