Patent ID: 8362979

Claim:
A plasma display device comprising: a plasma display panel including: a front plate including a first glass substrate on which display electrode pairs are formed, a dielectric layer covering the display electrode pairs, and a protective layer formed on the dielectric layer; a back plate disposed facing the front plate, the back plate including a second glass substrate on which data electrodes are formed such that the data electrodes of the back plate are facing the display electrode pairs of the front plate; and discharge cells formed between positions where the display electrode pairs are facing the data electrodes; and a panel driving circuit for driving the plasma display panel such that a plurality of subfields are temporally disposed to form one field period, each subfield of the plurality of subfields having an initializing period for causing an initializing discharge, an address period for causing an address discharge, and a sustain period for causing a sustain discharge in the discharge cells, wherein the protective layer includes: a base protective layer formed of a thin film containing a metal oxide; and a particle layer formed by discretely sticking, to the base protective layer, agglomerated particles in which a plurality of single-crystal particles of magnesium oxide are aggregated by static electricity between the plurality of single-crystal particles of magnesium oxide and are distributed across the entire surface of the base protective layer, wherein the panel driving circuit is configured to drive the plasma display panel such that, in the initializing period of a subfield of the plurality of subfields, one of (i) an all-cell initializing operation causing the initializing discharge in all of the discharge cells and (ii) a selective initializing operation causing the initializing discharge in discharge cells having undergone the sustain discharge is performed, and wherein the plurality of subfields are temporally disposed such that a luminance weight is monotonically decreased from (i) a subfield in which the all-cell initializing operation is performed to (ii) a subfield in which a next all-cell initializing operation is performed.
