Patent ID: 7455916

Claim:
An organic electroluminescent element comprising at least one pair of electrodes comprising an anode and a cathode, at least one of which is light transmissive, and at least one organic compound layer disposed between the electrodes, wherein the at least one organic compound layer contains at least one kind of non-conjugated polymer having terminal groups at terminal ends of the main chain of the non-conjugated polymer and both terminal groups of the non-conjugated polymer contain a fluorescent substance emitting fluorescence in a solid state; wherein the fluorescent substance emitting fluorescence in a solid state is selected from the group consisting of a compound having a substituted or unsubstituted monovalent polynuclear aromatic hydrocarbon having an aromatic ring number of 2 to 10, a compound having a substituted or unsubstituted monovalent condensed aromatic hydrocarbon having an aromatic ring number of 2 to 10, and a compound having a substituted or unsubstituted monovalent aromatic heterocyclic ring.
