PLASMA DISPLAY PANEL AND METHOD FOR PRODUCING SAME

摘要

A plasma display panel is disclosed wherein the sustaining voltage is stabilized and decrease in phosphor luminance is suppressed. In the plasma display panel, a magnesium oxide (MgO) protective film (14), to which an oxide having an electronegativity of not less than 1.4 is added, is formed on a dielectric glass layer (13) as the magnesium oxide (MgO) protective film (14). Consequently, adsorption of impurity gases onto the protective film (14) can be suppressed, and therefore the sustaining voltage is stabilized and decrease in phosphor luminance is suppressed.
