DIELECTRIC FORMATION MATERIAL AND DIELECTRIC FORMATION PASTE

摘要

PROBLEM TO BE SOLVED: To provide a high-contrast color image by composing a dielectric formation material used for forming a transparent dielectric layer for a front glass substrate of a plasma display panel with glass powder containing Nd2O3. SOLUTION: This dielectric formation paste is a dielectric formation paste used for forming a transparent dielectric layer for a front glass substrate of a plasma display panel, and contains glass powder containing Nd2O3 as a solid constituent. The transparent dielectric layer is formed on the front glass substrate to the extent of around 20-40μm in order to maintain the discharge of a display electrode, and it is naturally required for the dielectric layer to have a high breakdown voltage and excellent transparency. For this dielectric formation material, glass powder formed of glass having an absorption band in a wavelength region excluding that of luminescent color of a phosphor is used. When such glass is used, transmittance in the wavelength region excluding that of luminescent color of the phosphor within the light passing the transparent dielectric layer is lowered, so that contrast is improved.
