DIELECTRIC MATERIAL FOR PLASMA DISPLAY PANEL AND GLASS PLATE FOR PLASMA DISPLAY PANEL

摘要

Disclosed are a dielectric material which is for a plasma display panel and which enables a dielectric layer having high transmittance and a low dielectric constant to be obtained, and a glass plate which is for a plasma display panel and which comprises a dielectric layer having high transmittance and a low dielectric constant. The dielectric material for a plasma display panel contains a glass powder which contains virtually no PbO and contains, by mole percentage, 26-45% B2O3, 42-57% SiO2, 1-8% Al2O3, 0-10% Na2O, 1-15% K2O (wherein Na2O + K2O is 4-20%), 0-5% ZnO, and 0-6% CuO + MoO3 + CeO2 + MnO2 + CoO.
