ABSTRACT:
During manufacture of electroluminescent elements, layers of material are deposited upon a substrate as it is moving in a vacuum chamber beneath masks that shield the terminal regions of transparent electrodes formed upon the substrate. The masks are arranged so as to not contact the substrate, and are placed between the layer-forming material source. First insulation films, the light-emitting layers, or the second insulation films, or combinations thereof may be deposited using the method.
