• We studied the application of precursor solutions that can be fired into oxides to form a protective layer for AC-type Plasma Display Panel (AC-PDP) . Our study of alkoxide and metallic soap as MgO precursors revealed that the crystallinity of MgO films depends on the starting substance.Since the electric discharge characteristics of a panel and the lamination effect of the protective layer depend on precursors, it was confirmed that binders having higher crystallinity provide better characteristics. Our study revealed that a compound-oxide film has high crystallinity. The application of a Ba_<0.6>Sr<0.4>Gd_2O_4formation solution to a binder and the application of a Sr_<0.6>Mg_<0.4>Gd_2O_4 formation solution to a protective layer both are seemed promising. We also found that a double-layer film, made by forming a protective layer of fine MgO powder and a Ba_<0.6>Sr_<0.4>Gd_2O_4 binder, on top of a protective layer made of fine MgO powder and a MgO binder, provides a luminous efficiency 5.3times higher than that of sputtered M.gO film which is one of candidates for the large panel, and the conventional electron beam evaporation is not suitable for the large panel. We further found that a triple-layer protective film made by forming a thin film of Sr_<0.6>Mg_<0.4>Gd_2O_4 provides low voltages of I V in firing voltage (V_f) and 35 V in sustaining voltage (V_s) compared to the double-layer film and provides a luminous efficiency 5.5 times higher than that of sputtered MgO film. A life test revealed the triple-layer film in particular providing a useful life of more than 10,000 hours. From these findings, we concluded that the compound-oxides which is composed of alkaline-earth-metal and rare-earth-element could be applied effectively to a protective layer for AC-PDP.
