A backplate for a display panel, a display panel embodying such backplate, and methods for producing the backplates. The backplate comprises a thin layer of a glass-ceramic that receives the active display material on its surface, the glass-ceramic being sufficiently refractory to withstand a processing temperature of at least 850° C., that has a coefficient of thermal expansion over about 40×10 /° C., but not over about 100×10 /° C., and that has a crystal phase selected from spinel, enstatite, wollastonite, diopside, mullite, alpha-quartz, sapphirine, forsterite, beta-quartz, other alkaline earth metal silicates and aluminosilicates and mixtures of these crystal phases.
