The invention is a multi-color luminescent display 10 comprising an insulator substrate 11 and a single layer of host material 13 which may be a phosphor deposited thereon that hosts one or more differential impurities 14, therein forming a pattern of selected and distinctly colored phosphors such as blue, green, and red phosphors in the single layer of host material 13. Transparent electrical conductor means 12 may be provided for subjecting selected portions of the pattern of colored phosphors to an electric field thereby forming a multi-color, single layer electroluminescent display.
