Abstract
In a plasma display panel, a protective layer of a front plate includes a base protective layer and a particle layer. The base protective layer is formed of a thin film containing magnesium oxide. The particle layer is formed by sticking, to base protective layer, agglomerated particles in which a plurality of single-crystal particles of magnesium oxide are agglomerated. A panel driving circuit drives the panel in a manner that subfields are temporally disposed so that a luminance weight is monotonically decreased from a subfield in which an all-cell initializing operation is performed to a subfield immediately preceding a subfield in which a next all-cell initializing operation is performed.
