    Abstract: A light emitting device includes: a first electrode; a second electrode facing the first electrode; m emission units stacked between the first electrode and the second electrode; and m−1 charge generating layer(s) between the two adjacent emission units from among the m emission units, m−1 charge generating layer(s) including m−1 n-type charge generating layer(s) and m−1 p-type charge generating layer(s), wherein m is an integer of 2 or greater, a maximum emission wavelength of light emitted from at least one of the m emission units differs from that of light emitted from at least one of the other emission units, at least one of the m−1 n-type charge generating layer(s) includes a metal-containing material and an electron transporting metal-non-containing material.
