Claim 17:
18. The organic light-emitting device of claim 1, wherein the m−1 n-type charge generation layers include a metal-free compound containing at least one 7 electron deficient nitrogen-containing ring, a compound represented by Formula 601, a metal-containing material, or any combination thereof:

[Ar601])xe11-[(L601)xe1-R601])xe21,  Formula 601

wherein, in Formula 601,
Ar601 is a substituted or unsubstituted C5-C60 carbocyclic group or a substituted or unsubstituted C1-C60 heterocyclic group,
xe11 is 1, 2, or 3,
L601 is selected from a substituted or unsubstituted C3-C10 cycloalkylene group, a substituted or unsubstituted C1-C10 heterocycloalkylene group, a substituted or unsubstituted C3-C10 cycloalkenylene group, a substituted or unsubstituted C1-C10 heterocycloalkenylene group, a substituted or unsubstituted C6-C60 arylene group, a substituted or unsubstituted C1-C60 heteroarylene group, a substituted or unsubstituted divalent non-aromatic condensed polycyclic group, and a substituted or unsubstituted divalent non-aromatic condensed heteropolycyclic group,
xe1 is an integer from 0 to 5,
R601 is selected from a substituted or unsubstituted C3-C10 cycloalkyl group, a substituted or unsubstituted C1-C10 heterocycloalkyl group, a substituted or unsubstituted C3-C10 cycloalkenyl group, a substituted or unsubstituted C1-C10 heterocycloalkenyl group, a substituted or unsubstituted C6-C60 aryl group, a substituted or unsubstituted C6-C60 aryloxy group, a substituted or unsubstituted C6-C60 arylthio group, a substituted or unsubstituted C1-C60 heteroaryl group, a substituted or unsubstituted monovalent non-aromatic condensed polycyclic group, a substituted or unsubstituted monovalent non-aromatic condensed heteropolycyclic group, —Si(Q601)(Q602)(Q603), —C(═O)(Q601), —S(═O)2(Q601), and —P(═O)(Q601)(Q602),
Q601 to Q603 are each independently a C1-C10 alkyl group, a C1-C10 alkoxy group, a phenyl group, a biphenyl group, a terphenyl group, or a naphthyl group, and
xe21 is an integer from 1 to 5.
