Abstract
A method for manufacturing an organic electroluminescent display device in which a patterning of an organic electroluminescent layer can be carried out without the use of photolithography or metal masking. A transparent electrode and a hole transporting layer are formed on an anode board. Three kinds of layer-stacked devices each emitting light having one of primary colors of red, green and blue, composed of a metal strip and an organic electroluminescent layer covering around the metal strip are then formed. These layer-stacked devices are mounted on an insulation board in a manner that the organic electroluminescent layer faces upward. Then, the anode board and the insulation board are overlaid each other so that the transparent electrode intersects the layer-stacked device and that the hole transporting layer and the organic electroluminescent layer are opposed to each other.
