  • Patent number: 5912533
    Abstract: The invention relates to an easily fabricated and highly luminous electroluminescence (EL) device, whose front transparent electrode is made by using transparent conductive powder and transparent conductive binder, and a method for making such an EL device. The method comprises the steps of: providing a substrate; forming a metal electrode layer on the substrate, wherein the metal electrode layer reflects light incident thereto; forming a dielectric layer comprising a mixture of dielectric powder and a binder on the metal electrode layer; forming a phosphor layer including phosphor powder and a binder on the dielectric layer; and forming a transparent electrode layer including transparent conductive powder and a transparent conductive binder on the phosphor layer using a spin coating or a screen printing process employed for liquid material.
