<p>An organic EL device employing polymer material includes a structure in which a luminous layer formed of a polymer indicated by is put between a lower electrode and an upper electrode. In the above formula, Ar 1 , Ar 2 , which can be the same or different, denote arylene groups, R 1 , R 2 , R 3 , R 4 denote substituents, and n denotes the copolymerization ratio. The flatness of the luminous layer can be improved and the solubility of the luminous layer constituent material can be enhanced.</p> |
