Abstract
In a dielectric composition for use in formation of a dielectric layer in a plasma display panel, comprising glass powder, the glass powder is powder of glass which contains PbO of 50% or less and CuO as one of essential elements contained in the glass for preventing color change of the dielectric layer from being caused due to reaction with Ag electrodes in the plasma display panel. Ceramics powder can be mixed with the glass powder. The dielectric composition can also be provided in a form of paste, alternatively in a form of a green sheet.
