In a process for making an EL lamp, a rear electrode is roll coated on a temporary substrate, followed by successive roll coatings of a dielectric layer and a phosphor layer. A transparent, conductive layer on a transparent substrate is laminated to the phosphor layer layer and the temporary substrate is removed. The layers are applied from a slurry or ink and bladed to a uniform thickness across the width of the temporary substrate. The process can be continuous using rolls of material for the temporary substrate. The length of a lamp is limited by the length of the temporary substrate. The width of the lamp is determined by the size of the apparatus used to apply and to spread the layers.
