Abstract: PROBLEM TO BE SOLVED: To provide a member with high luminance that prevents the occurrence of short circuit between electrodes, by mainly containing electric conductive glass with volume resistivity in a specific range and a thermosoftening temperature in a specific range, in a dielectric layer for coating an electrode formed on a substrate.

Abnormal discharge caused by residual wall charge is prevented by applying electric conductivity to the dielectric layer. The electric conductivity is applied to a glass material itself constructing a dielectric to reduce effect of a phosphor to luminescence and to keep reflectance of the dielectric layer. In other words, luminance of the PDP is suppressed from decreasing.  Because partial excess increase of the electric conductivity caused by localizing of conductive micro particles, namely phenomena such as short circuit between electrodes, is suppressed, reliability of the plasma display panel is improved.
