Patent ID: 8268193

Claim:
A polymer composition for organic electroluminescence comprising a polymer material as a charge transport material or a light emitter, and a crosslinking agent, characterized in that the crosslinking agent comprises no aromatic ring; wherein the crosslinking agent is penta- or more functional; wherein the crosslinking agent is contained in a range of 1 to 99 mass % based on 100 mass % of the polymer material; and wherein the polymer material has a repeating unit derived from an aromatic amine represented by the following chemical formula (2): wherein, Ar 4 , Ar 5 , Ar 6 and Ar 7 each independently denotes an arylene group or a bivalent heterocyclic group; Ar 8 , Ar 9 and Ar 10 each independently denotes an aryl group or a monovalent heterocyclic group; and o and p each independently denotes 0 or 1, and 0≦o+p≦2.
