An organic EL device capable of being produced by a wet film forming method in which all processes can be conducted consistently under an inert atmosphere for efficiently forming a predetermined pattern without using any aqueous or acidic material. The device includes an organic layer between an anode and a cathode, the anode and the cathode facing each other, and the organic layer containing at least a light emitting layer. At least one layer composing the organic layer is a cured film having a predetermined pattern and containing a cured dendrimer material having one or more photoreactive functional groups at the ends thereof. The organic electroluminescent device is produced by: forming a dendrimer material layer, as at least one layer composing the organic layer, from a coating liquid containing a dendrimer material having one or more photoreactive functional groups at the ends thereof and an organic solvent; and pattern-exposing the dendrimer material layer.
