摘要： Embodiments provide a light-emitting device and an electronic apparatus including the light-emitting device. The light-emitting device includes a first electrode, a second electrode facing the first electrode, m emitting units between the first electrode and the second electrode, and m−1 charge generation layers between adjacent ones of the m emitting units, and each including an n-type charge generation layer and a p-type charge generation layer, wherein m is an integer of 2 or more, and at least one emitting unit of the m emitting units includes a first emission layer, a second emission layer, a first electron transport layer, a second electron transport layer, and a third electron transport layer.
