PROCESS FOR PRODUCING PLASMA DISPLAY PANEL

摘要

Disclosed is a process for producing a plasma display panel which has a discharge space and a protective layer that faces the discharge space. A gas comprising a reducing organic gas is introduced into the discharge space to thereby expose the protective layer to the reducing organic gas. The reducing organic gas is then discharged from the discharge space. Subsequently, a discharge gas is enclosed in the discharge space. The protective layer includes a nanoparticle layer comprising nanocrystal grains of metal oxides comprising a first metal oxide and a second metal oxide. The nanoparticle layer, in X-ray diffraction analysis, has at least one peak. Said peak is present between the first peak assignable to the first metal oxide in X-ray diffraction analysis and the second peak assignable to the second metal oxide in X-ray diffraction analysis. The first peak and the second peak show the same planar orientation as said peak.
