Abstract
A method of producing an organic EL element that allows easier patterning of the organic EL layer and reduction of the damage of the electrode layer caused by the organic EL layer and is superior in emission characteristics. Also provided is an organic electroluminescence element, including a substrate, a first electrode layer, a wettability variable layer, an organic EL layer, and a second electrode layer sequentially laminated. The wettability variable layer changes its wettability under the action of a photocatalyst caused by energy irradiation, is inactive to the energy, and has on the surface, a wettability variable pattern having an organopolysiloxane-containing lyophilic region and a liquid repellent region containing a fluorine-containing organopolysiloxane.
