Abstract
A light-emitting device and an apparatus including the same include a first electrode, a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, wherein the organic layer includes m emission units and (m−1) charge generating units, each of the charge generating units being between the emission units that are adjacent to each other, m is a natural number of 2 or greater, at least one of the (m−1) charge generating units includes an n-type charge generating layer, a p-type charge generating layer, and a p-type hole injection layer, wherein the n-type charge generating layer includes an n-type organic compound and a metal material, and wherein the p-type charge generating layer and the p-type hole injection layer each independently include an inorganic semiconductor material.
