Patent ID: 8292685

Claim:
A method for producing a plasma display panel having a rear plate and a front plate sealed to the rear plate with a discharge space interposed therebetween, wherein the front plate includes a dielectric layer and a protective layer which covers the dielectric layer, the protective layer including a base layer formed on the dielectric layer, agglomerated particles in which crystal particles of magnesium oxide are agglomerated to one another are dispersed evenly on an entire surface of the base layer, the base layer includes at least a first metallic oxide and a second metallic oxide, and has at least a peak through an X-ray diffraction analysis, the peak of the base layer is present at an intermediate position between a first peak through an X-ray diffraction analysis of the first metallic oxide and a second peak through an X-ray diffraction analysis of the second metallic oxide, the first peak and the second peak indicate a plane orientation equal to a plane orientation indicated by the peak of the base layer, and the first metallic oxide and the second metallic oxide are two selected from a group consisting of magnesium oxide, calcium oxide, strontium oxide, and barium oxide, the method for producing the plasma display panel comprising: forming the base layer on the dielectric layer; then spreading an organic solvent, in which the agglomerated particles are dispersed, on the base layer to form a coating layer; and then drying the coating layer under a reduced pressure to form an organic solvent coating film on at least the base layer; next disposing the rear plate and the front plate on which the coating film is formed so as to face each other; then heating the front plate and the rear plate facing each other to evaporate the coating film, dispersing the agglomerated particles on the base layer, and removing components of the evaporated coating film from the discharge space; and then sealing the rear plate and the front plate from which the coating film is evaporated to each other.
