A polymer electroluminescent display is provided which comprises a number of individual light-emitting elements in a selected formation and adapted for excitation from a voltage supply. The formation, which is formed on a substrate, includes copper conductors etched onto the substrate. a plurality of polymer dielectrics with relatively high dielectric constant are screen printed over the 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 polymer dielectric with a relatively low dielectric constant separates each of the individual light-emitting elements from each other and alleviates cross-talk between the individual light-emitting elements. 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 location.
