Provided is a structure of an organic EL device capable of reducing the product cost by drastically simplifying the fabrication process as compared with a conventional multi-photon organic EL device. An insulating organic material layer having a low dielectric constant is placed to smooth the transfer of electron carriers between a strong electron-accepting material layer and an electron transport layer included in a charge generating layer of the conventional multi-photon organic EL device. |
