A method for manufacturing an organic EL device in accordance with the invention
includes: 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.
