Plasma display panel and method for producing same

摘要

The preresent invention provides a plasma display panel that suppresses discharge sustain voltage, and reduces brightness degradation of a phosphor. In the plasma display panel, as protective film ( 14 ) made of magnesium oxide (MgO) formed on dielectric glass layer ( 13 ), protective film ( 14 ) made of magnesium oxide (MgO) with oxide added with an electronegativity of 1.4 or higher, is formed to suppress impure gas adsorption by protective film ( 14 ), stabilizes discharge sustain voltage, and reduces brightness degradation.
