Barrier ribs material for a plasma display panel

摘要

In a PDP barrier ribs material comprising glass powder and silica-based filler powder, the silica-based filler powder comprises fused silica powder and alpha-quartz powder. At least a part of the silica-based filler powder is spherical filler powder. The remaining part of the silica-based filler powder may be aspherical filler powder. In this case, the ratio of the spherical filler powder and the aspherical filler powder may be 30:70 to 100:0 in mass ratio.
