<p>An object of the present invention is to provide a polymer which shows a high excited singlet level and a high excited triplet level, which has excellent charge transporting ability and excellent electrochemical stability, which enables formation of multiple layers, which is scarcely decomposed, and which can provide a uniform film quality, and to provide an organic electroluminescent element material and an organic electroluminescent element composition, and to provide an organic electroluminescent element which shows a high light-emitting efficiency and drivability at a low voltage and a high driving stability, and a display device and a lighting device. The present invention relates to a polymer comprising a repeating unit represented by the following general formula (1) and a cross-linkable group (wherein Ar 11 to Ar 13 each independently represents a divalent aromatic group which may have a substituent, Ar 14 and Ar 15 each independently represents an aromatic group which may have a substituent, Ar 16 and Ar 17 each independently represents a direct bond or a divalent aromatic group which may have a substituent, R 11 and R 12 each independently represents a hydrogen atom, an alkyl group which may have a substituent, an alkoxy group which may have a substituent, or an aromatic group which may have a substituent, r represents an integer of from 0 to 5, and R 11 and R 12 may be connected to each other to form a ring structure, in which the repeating unit represented by the above-described general formula (1) may contain the cross-linking group):</p> |
