A feature of the present invention is to reduce production cost in a method for manufacturing an organic EL device including a step of forming a light-emitting layer having a predetermined pattern by an ink-jet method. Means for achieving the object is to not form a bank which surrounds an area in a substrate surface other than an area at which a light-emitting layer 5 is formed. A solution-repellent treatment is performed so that a droplet 50 of a liquid containing a light-emitting material has a contact angle of 15° to 90° with respect to the substrate surface immediately before formation of the light-emitting layer 5. Accordingly, a fluorine containing layer (a layer composed of a material containing fluorine) 4 is formed. Between a step of forming the light-emitting layer 5 and a step of forming a cathode 7, a step of forming a hole blocking layer 6 over the entire surface of the substrate is performed.
