摘要：
In a plasma display panel, a protective layer of a front plate is formed of a base protective layer and a particle layer. The base protective layer is a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. The particle layer is formed in a manner that single-crystal particles of magnesium oxide having a peak of emission intensity at 200-300 nm two times or higher than another peak of emission intensity at 300-550 nm in the emission spectrum in cathode luminescence emission are stuck on the base protective layer. A panel driving circuit drives the plasma display panel with a subfield structure in which subfields are temporally disposed so that a magnitude of luminance weight has a monotonous decrease from a subfield where an all-cell initializing operation is performed to a subfield where a next all-cell initializing operation is performed.
