Embossed plasma display back panel

A plasma display device having a composite back panel including a metal substrate having a predetermined thermal coefficient of expansion (TCE) and a ceramic barrier rib structure which are co-fired at a pre-determined temperature, the ceramic barrier rib structure is composed from a first glass material having a TCE which is less than the TCE of the metal substrate, the first glass formulated to flow-back at the co-firing temperature; and a second glass material having a TCE which is greater than the TCE of the metal substrate, wherein the first and the second glass materials are mixed in a proportion to produce a composite ceramic material having a TCE which is substantially equal to the TCE of the metal substrate. The plasma display device having the ceramic barrier rib structure composed of the first and second glasses provides control of the TCE to minimize stresses in the final produce and assure panel flatness. A green ceramic tape defined by percentage weight formulation as: 40-70% glass 1, 1-15% glass 2, 10-30% solvent, 10-40% resin, wherein glass 1 is defined by percentage weight formulation as: 15-50% ZnO, 10-45% MgO, 5-30%, BaO, 10-45% SiO2, and glass 2 is defined by percentage weight formulation as: 10-80% SiO2, 5-60% B2O3, 5-30% BaO, 0-60% Al2O3. The green tape ceramic including the aforementioned glass 1 and glass 2 promotes solidification and densification.
