PURPOSE: A dielectric composition of plasma display panel is provided to reduce a coefficient of thermal expansion of the front substrate and to enhance an anti-shock strength by controlling contents of PbO, B2O3 and SiO2. CONSTITUTION: The dielectric composition of plasma display panel includes PbO of 45-50wt%, B2O3 of 15-19wt% and SiO2 of 6-10wt%. The BaO is included 4-10wt% more. The TiO2 is included 2-5wt% more. The dielectric composition of plasma display panel includes pbO of 65-70wt%, B2O3 of 5-10wt% and SiO2 of 15-20wt%. |
