Abstract: An electroluminescent panel and a method of manufacturing the same which comprises: forming a roll of luminous base film which includes a luminous layer made of phosphors embedded in an insulating material, the luminous layer being laminated upon a conductive film; forming a roll of a transparent conductive film; passing the luminous base film and the transparent conductive film between a pair of rollers while sandwiching a power supply bus bar made of a metal film therebetween, to thereby form the luminous film, the transparent conductive film and the power supply bus bar into an integrated body by means of pressurized heating; cutting the integrated body into at least one piece having a predetermined length; and mounting a terminal to the at least one piece packaging the at least one piece with a moisture proof film.

Abstract: An elongated EL element and a manufacturing method thereof. An elongated substrate has a back electrode, an insulating layer and a luminescent layer which are superimposed upon each other. A transparent conductive film is superimposed upon the substrate. An auxiliary electrode narrower in width than that of each of the substrate and the transparent conductive film has an insulating film, a conductive metal layer and a conductive adhesive layer which are superimposed upon each other. The auxiliary electrode is sandwiched between the substrate and the transparent conductive film superimposed one upon the other, and extends longitudinally of the substrate and the transparent conductive film, wherein the insulating film is in contact with the luminescent layer of the substrate, while the conductive adhesive layer is bonded to the transparent conductive film. An assembly of the substrate, the transparent conductive film and the auxiliary electrode is covered sealingly with dampproof film material.
