  • Patent number: 7723627
    Abstract: An EL sheet and a member for lighting a push-button switch capable of emitting light stably and sufficiently for a long period of time without trouble such as non-light emission phenomena and generation of black dot, even if the EL element is subjected to, for example, a drawing process to form into a three dimensional shape, includes a counter electrode layer 15, dielectric layer 14, light-emitting layer 13, and transparent electrode layer 11. An adhesive layer 12 made of adhesive having excellent adhesiveness to the electroconductive polymer is disposed between the transparent electrode layer 11 made of an electroconductive polymer and the light-emitting layer 13. As for the adhesives having excellent adhesiveness, polyester, acrylic, cyanoacrylate, polyolefin, ethylene-vinyl acetate or ethylene ethyl acrylate type adhesive is used. The dielectric layer is made of fluoro type, polyester type or acrylic type resin binder.
