Claim 9:
10. An organic light-emitting device comprising:
a first electrode;
a second electrode; and
an organic layer between the first electrode and the second electrode,
wherein the organic layer comprises:
an emission layer;
a hole transport region between the first electrode and the emission layer; and
an electron transport region between the emission layer and the second electrode,
wherein 50% or more of a total volume of the second electrode is silver (Ag), the hole transport region comprises an amine-based polymer comprising a first repeating unit represented by Formula 1, and a number average molecular weight of the amine-based polymer is about 1,000 or more,
wherein the hole transport region comprises a hole injection layer and a hole transport layer, both of the hole injection layer and the hole transport layer comprises the amine-based polymer:, wherein, in Formula 1,
L11 to L13 are each independently selected from 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,
n11 to n13 are each independently selected from 0, 1, 2, and 3,
R11 is selected from 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 C1-C60 heteroaryl group, a substituted or unsubstituted monovalent non-aromatic condensed polycyclic group, and a substituted or unsubstituted monovalent non-aromatic condensed heteropolycyclic group, and
* and *′ each indicate a binding site to a neighboring atom, and
wherein
the amine-based polymer included in the hole injection layer further comprises a second repeating unit represented by Formula 1, the second repeating unit is different from the first repeating unit, and
the amine-based polymer included in the hole transport layer comprises a second repeating unit represented by Formula 2-1 and a third repeating unit represented by Formula 2-1,
wherein the second repeating unit and the third repeating unit are different from each other:, wherein, in Formula 2-1,
R22 and R23 are each independently selected from hydrogen, deuterium, —F, —Cl, —Br, —I, a cyano group, a nitro group, a C1-C20 alkyl group, a C1-C20 alkoxy group, a phenyl group, a biphenyl group, a terphenyl group, a phenyl group substituted with a C1-C10 alkyl group, a phenyl group substituted with —F, a naphthyl group, —Si(Q31)(Q32)(Q33), and —N(Q31)(Q32),
b22 is selected from 1, 2, and 3, and
R24 and R25 are each independently selected from a crosslinking group represented by one selected from Formulae 7-1 to 7-3, deuterium, a cyano group, a nitro group, a C1-C20 alkyl group, a C1-C20 alkoxy group, a phenyl group, a biphenyl group, a terphenyl group, a phenyl group substituted with a C1-C10 alkyl group, a phenyl group substituted with —F, a naphthyl group, —Si(Q31)(Q32)(Q33), and —N(Q31)(Q32):, wherein, in Formulae 7-1 to 7-3,
R71 is selected from hydrogen and a C1-C20 alkyl group,
b71 is selected from 1, 2, and 3,
Q31 to Q33 are each independently selected from a phenyl group, a naphthyl group, a fluorenyl group, a benzofluorenyl group, a dibenzofluorenyl group, a phenanthrenyl group, a thiophenyl group, a furanyl group, a pyridinyl group, a pyrimidinyl group, a triazinyl group, a carbazolyl group, a benzofuranyl group, a benzothiophenyl group, a dibenzofuranyl group, a dibenzothiophenyl group, a benzocarbazolyl group, and a dibenzocarbazolyl group, and
* and *′ each indicate a binding site to a neighboring atom,
R24 and R25 in a third repeating unit are each independently selected from a crosslinking group represented by one selected from Formulae 7-1 to 7-3, deuterium, —F, —Cl, —Br, —I, and a nitro group.
