ABSTRACT:
A method for manufacturing an organic EL device comprising: coating a composition including an organic EL material on a plurality of electrodes to form an organic EL layer on each electrode; defining an effectively optical area in which the plurality of electrodes are formed; and defining a coating area which is broader than the effectively optical area, on which the composition including an organic EL material is to be coated. According to this method, a uniform display device without uneven luminance and uneven chrominance within a pixel or among a plurality of pixels in the effectively optical area can be obtained.
