Abstract
A method of producing an organic electroluminescent element according to the present invention is a method of producing an organic electroluminescent element by stacking on a substrate at least a cathode, an anode, and an organic light-emitting layer disposed between the cathode and the anode. The method of the present invention is characterized by comprising: an organic light-emitting layer forming step of forming the organic light-emitting layer by applying an ink comprising an organic light-emitting material to an inside of a partition wall built to surround a pixel region for forming a pixel; and a surface treating step of treating a surface before the organic light-emitting layer forming step with an organic solvent from the side where the partition wall is built with respect to the substrate. According to the method of the present invention, the organic light-emitting layer can be formed without film defects, and a high-quality organic electroluminescent element and a high-quality display device having the organic electroluminescent element are provided.
