Summary: | Embodiments provide a light-emitting device, an electronic apparatus including the light-emitting device, and an electronic device including the light-emitting device. The light-emitting device includes a first electrode, a second electrode, and an interlayer between the first electrode and the second electrode. The interlayer includes m emission units, and m−1 charge generation unit(s) between adjacent ones of the m emission units, wherein m is an integer of 2 or more. One of the m emission units includes an emission layer, an electron injection layer between the emission layer and the second electrode, and an electron transport layer between the electron injection layer and the emission layer. The electron injection layer includes a mixture of a first metal-containing material and a first metal-free material, and the electron transport layer does not include a lithium-containing material. |
