ABSTRACT:
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, Ar1, Ar2denote a allylene group respectively, R1, R2, R3, R4denote 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.
