Abstract: An improved dielectric layer of an electroluminescent laminate, and method of preparation are provided. The dielectric layer is formed as a thick layer from a ceramic material to provide: a dielectric strength greater than about 1.0 x 106 V/m; a dielectric constant such that the ratio of the dielectric constant of the dielectric material to that of the phosphor layer is greater than about 50:1; a thickness such that the ratio of the thickness of the dielectric layer to that of the phosphor layer is in the range of about 20:1 to 500:1; and a surface adjacent the phosphor layer which is compatible with the phosphor layer and sufficiently smooth that the phosphor layer illuminates generally uniformly at a given excitation voltage. The invention also provides for electrical connection of an electroluminescent laminate to voltage driving circuitry with through hole technology. The invention also extends to laser scribing the transparent conductor lines of an electroluminescent laminate.
