Patent ID: 8482490

Claim:
A plasma display device comprising: a plasma display panel including: a first substrate including (i) a pair of electrodes including a first electrode and a second electrode, (ii) a dielectric layer formed so as to cover the first electrode and the second electrode, and (iii) a protective layer formed on a surface of the dielectric layer; and a second substrate including (i) a third electrode, and (ii) a dielectric layer formed so as to cover the third electrode, wherein the first substrate and the second substrate are positioned so as to face each other, wherein a discharge gas is sealed between the first substrate and the second substrate, 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 one field is formed of a plurality of subfields, wherein each of the subfields has an initializing period, an address period, and a sustain period, and wherein the initializing period has a first half of the initializing period in which the second electrode is applied with a voltage gradually rising from a first voltage to a second voltage, and a second half of the initializing period in which the second electrode is applied with a voltage gradually falling from a third voltage to a fourth voltage.
