An object of the present invention is to improve image display quality in a plasma display panel used for an image display device and to stably maintain the image display quality for a long period of time. A plasma display panel in which a first electrode and a second electrode constituting a main electrode pair are covered with an insulating layer with respect to a discharge gas, wherein at least the discharge gas of the dielectric glass layer 13 and A protective film 14 is provided as a contacting surface layer, and at least a part of the surface layer is covered with a material having a lower value than the standard generation enthalpy, such as magnesium hydroxide, magnesium carbonate, magnesium hydrogen carbonate, magnesium nitrate, and magnesium sulfate. It is configured. [Selection] Figure 2 |
