Abstract
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.
Claims11
A method for manufacturing an organic EL device, comprising:
- coating a composition including an organic EL material above a plurality of electrodes to form an organic EL layer above each of the plurality of electrodes;
- defining an effectively optical area in which the plurality of electrodes are formed;
- and
- defining a coating area, that is broader than the effectively optical area, in which the composition including the organic EL material is to be coated.
A method for manufacturing an organic EL device which includes an effectively optical area having a plurality of electrodes and an organic EL layer formed above each of the plurality of electrodes, the method comprising:
- forming the organic EL layer both on areas that are to be the effectively optical area and on other areas that are not to be the effectively optical area.
A method for manufacturing an organic EL device which includes an effectively optical area having a plurality of electrodes and an organic EL layer formed above each of the plurality of electrodes, the method comprising:
- forming the organic EL layer in areas not having the electrodes and which are supposed to be the effectively optical area.
