An organic EL device employing polymer material includes a structure in which a luminous layer formed of a polymer indicated byis put between a lower electrode and an upper electrode. Where, in the above chemical formula, Ar<1>, Ar<2 >denote a allylene group respectively, R<1>, R<2>, R<3>, R<4 >denote a substituent respectively, and n denotes a copolymerization ratio. Accordingly, the flatness of the luminous layer can be improved and the solubility of the luminous layer constituent material can be enhanced.
