Abstract
An organic EL element includes a functional layer disposed between an anode and a cathode on a substrate and including laminated different organic thin films including a light-emitting layer, and a partition wall which defines the functional layer. Each of the organic thin films is formed by applying a liquid containing a functional layer-forming material on a film-forming region defined by the partition wall and then drying the liquid. The partition wall has at least one step portion provided in the side wall thereof in the thickness direction, and liquid repellency is imparted to the uppermost surface of the partition wall and the upper surface of the step portion. The surface of the side wall excluding the step portion has lyophilicity in comparison with the upper surface of the step portion.
