ABSTRACT:
An electroluminescent lamp has a face side laminated film and a rear side laminated film. The face side laminated film is constituted by sequentially formed layers including a transparent electrode, a luminous layer formed of a moistureproof-coated phosphor powder distributed in fluororesin such as vinylidene fluoride which is a low hygroscopic resin, and a reflective insulation layer formed of a high dielectric material distributed in fluororesin. The rear side laminated film is constituted by sequentially formed layers including a film such as a PET film, an adhesive layer, and a rear electrode which is formed of a conductive material such as carbon paste or nickel paste having a migration property lower than that of silver (Ag) and which is thermally-compress-bonded to the reflective insulation layer. This arrangement makes it possible to omit such outer coat films and hygroscopic films as used in the prior art arrangement.
