ABSTRACT:
An electroluminescent device having improved moisture resistance. The device comprises a transparent substrate having a transparent electrode layer. A luminescent layer and a dielectric layer are interposed between the transparent electrode layer and a back electrode layer. The luminescent layer comprises a resinous binder containing electroluminescent particles. The dielectric layer comprises a resinous binder containing dielectric particles. The back electrode layer comprises a resinous binder containing conductive particles. The resinous binder of at least one of the luminescent layer and the dielectric layer is made from a fluoride resin. A reaction accelerator for promoting polymerization of the fluoride resin is contained in the back electrode layer.
