Claim Text:
1. An organic light-emitting device, comprising: a first electrode; a second electrode facing the first electrode; an emission layer (EML) disposed between the first electrode and the second electrode; a hole transporting region between the first electrode and the EML; and an electron transporting region between the EML and the second electrode, wherein: the hole transporting region includes an amine-based compound represented by one of Formulae 1A and 1C:  and the EML includes a host and a dopant, the dopant includes an organic metal complex and the host includes a compound represented by one of Formulae Formula 2, 10A, and 10E: wherein Z A ring A and ring B are each independently selected from i) a benzene or a naphthalene; and ii) a benzene or a naphthalene, each substituted with at least one of a deuterium atom, a halogen atom, a C C X X R Y Y X E L a C a C a1, a2, and a11 are each independently an integer selected from 0 to 5; Ar a C a C R a hydrogen, a deuterium, a halogen atom, a hydroxyl group, a cyano group, a nitro group, an amino group, an amidino group, a hydrazine group, a hydrazone group, a carboxylic acid group or a salt thereof, a sulfonic acid group or a salt thereof, a phosphoric acid group or a salt thereof, a C a C a C a C —N(Q p, b1, b2, b3, and b4 are each independently an integer selected from 1 to 4; q is an integer of 1 or 2; and n1 and n2 are each independently an integer selected from 0 to 3, wherein the amount of the organic metal complex is selected from a range of about 0.01 to about 15 parts by weight based on 100 parts by weight of the host.
