A dielectric forming material for use as a transparent dielectric layer formed on an inside surface of a front glass substrate in a plasma display panel comprises powder of colored glass. The powder of colored glass comprises a base glass and coloring ingredients added thereto. The coloring ingredients comprise CoO and NiO. The powder of colored glass provides a glass film having a spectral transmittance T%(460 nm) of 50-75% at the wavelength of 460 nm or a glass film having a spectral transmittance T%(460 nm) higher than a spectral transmittance T%(550 nm) at the wavelength of 550 nm and a spectral transmittance T%(620 nm) at the wavelength of 620 nm. The glass film is formed by applying the colored glass powder onto a soda lime glass plate having a thickness of 1.7 mm and by baking the colored glass powder to form a baked film having a thickness of 20-40 μm as the glass film.
A dielectric forming material for use as a transparent dielectric layer formed on an inside surface of a front glass substrate in a plasma display panel, said dielectric forming material comprising powder of colored glass which essentially consists of a base glass and coloring ingredients added thereto, said coloring ingredients comprising CoO and NiO, and said colored glass is selected from the group consisting of
