A method of coating an electroluminescent device having a back electrode, a reflective insulating layer, a light emitting layer and a transparent electrode laminated with a moisture absorbing film or directly with an outer film, wherein the moisture absorbing film is used, the electroluminescence is performed. After encapsulating the element from the transparent electrode side toward the back electrode side with a moisture absorption film and a skin film, on the lower surface of the back electrode, both encapsulation end portions of the moisture absorption film are fusion-bonded at a distance. Both wrapping ends of the film are extended so as to be fused at intervals so as to cover the wrapping end of the moisture absorbing film, and when the moisture absorbing film is not used, the electroluminescent element is attached to the transparent electrode side. It is characterized in that it is wrapped directly with the outer film from the back electrode side toward the back electrode side, the wrapping end portion is extended, and the back surface of the back electrode is fused at intervals. A method of manufacturing a field emission lamp to.

せたことを特徴とする電界発光灯。2. An electroluminescent device comprising a back electrode, a reflective insulating layer, a light emitting layer, and a transparent electrode, which are laminated with a skin film via a hygroscopic film, wherein the electroluminescent device is backed from its transparent electrode side. The moisture-absorbing film wrapped toward the electrode side and the wrapping end portion of the outer film are fused on the lower surface of the back electrode at intervals.
An electroluminescent lamp characterized in that a back electrode is exposed between the wrapping ends of the outer film.

界発光灯。3. An electroluminescent device having a back electrode, a reflective insulating layer, a light emitting layer and a transparent electrode laminated, which is covered with an outer skin film, wherein the electroluminescent device extends from the transparent electrode side to the back electrode side. An electroluminescent lamp comprising a wrapping, an wrapping end portion extended, and the lower surface of the back electrode being fused at intervals so that the back electrode is exposed between the wrapping end portions of the outer cover film.
