ABSTRACT:
A glass composition for a plasma display panel (PDP) and its fabrication method are disclosed. The composition, including a ZnO—B2O3group and alkaline earth metal oxide, is environment-friendly, has a high discharge efficiency and is used as various PDP dielectric materials. The fabrication method allows to compose the low melting point unleaded non-alkali glass composition at a low cost.
