Plasma display panel

A plasma display panel comprising:

• a front plate;
• a rear plate disposed oppositely to the front plate;
• and
• a bonding layer to bond the front plate to the rear plate, wherein
• the front plate has a dielectric layer, and a protective layer to cover the dielectric layer,
• the protective layer includes a base layer formed on the dielectric layer,
• aggregated particles composed of aggregated crystal particles made of a magnesium oxide are dispersed all over the base layer,
• the base layer contains at least a first metal oxide and a second metal oxide,
• the base layer has at least one peak through an X-ray diffraction analysis,
• the peak exists between a first peak of the first metal oxide through an X-ray diffraction analysis, and a second peak of the second metal oxide through an X-ray diffraction analysis,
• the first peak and the second peak show the same surface orientation as a surface orientation shown by the peak,
• the first metal oxide and the second metal oxide are composed of two kinds of oxides selected from a group consisting of a magnesium oxide, a calcium oxide, a strontium oxide, and a barium oxide,
• the rear plate has barrier ribs, and
• the bonding layer bonds at least one part of the barrier ribs to the protective layer.
