An electroluminescent display is provided which comprises a matrix of individual light-emitting elements in a row and column formation and adapted for excitation from a voltage supply which addresses the matrix. The matrix, which is formed on a substrate, includes a plurality of parallel copper conductors etched onto the substrate with each of the conductors forming a column. A plurality of polymer dielectrics are screen printed over the first conductors, with each dielectric corresponding to an individual light-emitting element. A plurality of light-emitting polymer phosphors are screen printed over the dielectrics with each phosphor corresponding to an individual light-emitting element. A polymer indium oxide light-transmissive conductor is screen printed over each phosphor. A conductive silver polymer ink is printed over the light-transmissive conductor with portions of the silver polymer defining window openings for enabling viewing of the phosphor through the light-transmissive layer when the phosphor is excited. Voltage excitation by a dynamic voltage supply across a selected copper conductor and the silver polymer will cause light emission by the light-emitting element at the excited row-column intersection.
