Abstract
Protective layer () of front plate () of a plasma display panel has base protective layer () and particle layer (). Base protective layer () is formed of a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. Particle layer () is formed by sticking, to base protective layer (), single crystal particles () of magnesium oxide having an NaCl crystal structure that is surrounded by a specified two-type orientation face formed of (100) face and (111) face or a specified three-type orientation face formed of (100) face, (110) face, and (111) face. The panel driving circuit drives the panel while temporally disposing the subfields so that the luminance weight monotonically decreases from a subfield in which an all-cell initializing operation is performed to the subfield immediately before the subfield in which its next all-cell initializing operation is performed.
