ABSTRACT:
The present invention provides a process and apparatus for manufacturing organic electroluminescence cell, wherein the steps after formation of a transparent electrode on a substrate plate up to formation of a protective film are successively carried out in vacuum chambers which are isolated from the oxidative external atmosphere and thereafter withdrawn from the chambers into the air. A plurarity of layer portions of at least a portion of the electroluminescence cell is formed in a plurality of woriking chambers and withdrawn to the outside after formation of a protective film thereon.
