Abstract
A dispersive electroluminescence comprising a fluorescent layer coated on a transparent electrode, and an opposing electrode comprising a conductive layer in contact with the fluorescent layer and a low resistance external layer. The conductive layer is mainly composed of conductive fine particles, and majority of such conductive fine particles are three-dimensionally in contact with each other forming a conductive path and fill in the spaces in the surface of the fluorescent layer. The conductive layer is formed on the fluorescent layer by spraying a liquid composed of fine conductive particles dispersed in an organic liquid on the fluorescent layer and then drying it.
