Abstract
Abstract A solid-state image converting device comprises a transparent substrate, a transparent electrode formed on the transparent substrate, an EL layer, formed on the transparent electrode, emitting light by the application of an electric field, a dot-like low resistance layer formed on the EL layer, a photoconductive layer formed on the dot-like low resistance layer, and a back electrode formed on the photoconductive layer. A radiation image entered the transparent substrate or the back electrode is converted into a visible light image having high brightness on the back electrode or the transparent substrate.
