Abstract
An electroluminescence device having an excellent moisture-resistant property is disclosed. Such an electroluminescence device comprises a light emitting layer inserted between an opposite electrode and a transparent electrode to form a multi-layered structure, said structure being airtightly sealed by a pair of protective sheets and said ELD being able to be fitted to an external apparatus by means of a metal fixture. The ELD is characterized in that a metal composite film is formed by inserting a metal foil between a pair of resin films and is used for one of the protective sheets for said opposite electrode. The composite film having a notch which is formed by removing part of the metal foil around a portion of the metal composite film prepared to accommodate the metal fixture.
