For the purpose of realizing the very fine barrier electrode ac plasma displays, we fabricated the 0.5mm pitch test panels with the barrier ribs fabricated by sandblasting method. As a result, it is showed that the sandblasting method has enough accuracy to fabricate the finer barrier electrode ac plasma displays. And luminance of 125 cd/m^2 and luminous efficiency of 0.25 lm/W were obtained for the panel with the barrier ribs fabricated by sandblasting method.
