1. An organic electroluminescent element comprising:
a pair of electrodes including a positive electrode and a negative electrode, with at least one of the electrodes being transparent or semi-transparent; and an organic compound layer interposed between the pair of electrodes and containing one or more charge transporting polyesters represented by the following formula (I): wherein in the formula (I),A1 represents at least one selected from structures represented by the following formula (II);Y1 and Y2 each independently represent a substituted or unsubstituted divalent hydrocarbon group;m1 and m2 each independently represent an integer of from 1 to 5;p represents an integer of from 5 to 5,000; andR1 and R2 each independently represent a hydrogen atom or a phenyl group; wherein in the formula (II),Ar1and Ar2 each independently represent a substituted or unsubstituted phenyl group, a substituted or unsubstituted monovalent polynuclear aromatic hydrocarbon group having two aromatic rings, a substituted or unsubstituted monovalent condensed aromatic hydrocarbon group having two or three aromatic rings, or a substituted or unsubstituted monovalent aromatic heterocyclic group;j1 and j2 each independently represent 0 or 1;T1 and T2 each independently represent a divalent linear hydrocarbon group having from 1 to 6 carbon atoms, or a divalent branched hydrocarbon group having from 2 to 10 carbon atoms; andX represents a group represented by the following formula (III):
