Organic electroluminescence device

DETAILED DESCRIPTION We claim: 1.
An organic electroluminescence device which comprises a polycarbonate containing a repeating unit of a styrylamine skeleton having an electroluminesence function as at least one material selected from the group consisting of an emitting material and a hole injecting material.
2.
The organic electroluminescence device according to claim 1, wherein the styrylamine skeleton is a monovalent or divalent group formed by removing hydrogen atoms from a molecule wherein one aromatic tertiary amine is substituted by at least one arylvinylene or arylvinylene arylenevinylene group having 8 to 22 carbon atoms.
3.
The organic electroluminescence device according to claim 1 wherein the styrylamine skeleton is a divalent group formed by removing hydrogen atoms from a molecule comprising 2 or 3 aromatic tertiary amines and a vinylene group or a vinylenearylene vinylene group having 10 to 22 carbon atoms which combines said aromatic tertiary amines.
4.
The organic electroluminescence device according to claim 2 or 3, wherein a polycarbonate has a repeating unit comprising a styrylamine skeleton represented by the formula (I): ##STR136## wherein Ar.
