Abstract

An organic EL device having high luminous efficiency is provided. An organic EL device (1) has an inorganic material film (14) of titanium oxide on a transparent electrode film (12). Since the inorganic material film (14) exhibits higher affinity to a solvent such as water than the transparent electrode film (12), once a first organic material such as a hole-transporting material dispersed in a solvent is placed on the surface of the inorganic material film (14), the first organic material spreads over the surface of the inorganic material film (14), thereby forming a first organic layer (21) having a uniform thickness. Since the surface of the first organic layer (21) is flat, a second organic layer (22) having a uniform thickness can be formed when a second organic material is placed on the first organic layer (21). Since the first through third organic layers (21-23) constituting an organic film (20) respectively have a uniform thickness in the organic EL element (1), emission of the organic layer (22) containing a light-emitting substance can be uniform and high luminous efficiency is ensured.
