Organic electroluminescent display device and method of manufacturing the same
First Claim
1. A method for manufacturing an organic electroluminescent display device comprising:
- a first process of forming a patterned transparent electrode on an anode board;
a second process of forming a hole transporting layer on said transparent electrode;
a third process of forming three kinds of layer-stacked devices by sequentially stacking a metal cathode, organic electroluminescent layers each emitting red, green or blue color light on a surface of a piece of strip-like metal;
a fourth process of arranging said three kinds of layer-stacked devices with each of said organic electrouminescent layers facing upward on an insulation board;
a fifth process of overlaying said anode board and said insulation board each other so that said transparent electrode and said layer-stacked devices intersect each other and that said hole transporting layer and said organic electrouminescent layer are opposed to each other; and
a sixth process of making sealing around said anode board and said insulation board being overlaid each other.

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.
