The transparent conductive electrode 1 is made by depositing a gold If oxide thin film of InO2-8n02'I on one side of a transparent plastic film 20. The phosphor layer 3 is made of ZnS
A phosphor obtained by doping a phosphor with an activator such as copper, chloride, etc. and an activator such as chlorine is dispersed in an electric resin. Insulation No. 4 is BaTiO3, TiOH, etc. 11! i Dielectric powder r Dispersed in a high dielectric resin. Back side electric disaster 5 is made up of AI failure.

し、その内面［吸ｃＭフイルム層を設けて捕水し、蛍光
体層に水分が達しないようにする。Organic dispersion type EL panel G engineering, when AC voltage is applied between both electrodes, the phosphor emits light. However, if there is moisture, the phosphor deteriorates and the brightness deteriorates rapidly. As a countermeasure against this problem, the entire structure is sound-sealed using trichlorethylene chloride film, which has low moisture permeability, and a cM-absorbing film layer is provided on the inner surface of the film to catch water and prevent moisture from reaching the phosphor layer.

り？生ずる問題がある。The above-mentioned moisture-absorbing film 6 is usually a nylon film, and from the outside, a 32-chloride ethylene film is used as a moisture-proof film, and the film is sealed. In addition, although nylon film and 32-fluoroethylene chloride are laminated, warping and chamfering are likely to occur due to the difference in heat shrinkage between the two.
As a result, the entire EL panel warps. Also, since the back electrode is made of AI foil, there is a two-layer structure on the outside that is moisture-absorbing and moisture-proof. λ and only the outside of the transparent electrode KJ:
Increased moisture absorption and moisture resistance by 2? Is there even more warping when laminated? There are problems that arise.
