BARRIER RIB MATERIAL FOR PLASMA DISPLAY PANEL AND POWDERY FILLER

摘要

PROBLEM TO BE SOLVED: To provide a powdery filler that has a low dielectric constant and can be used as a substitute for powdery alumina (one of main components of a conventional plasma display panel barrier rib material) and to provide a barrier rib material for a plasma display panel, which contains this powdery filler and is capable of forming a dense barrier rib having a low dielectric constant. SOLUTION: This powdery filler consists of glass which has a composition comprising 21-49 mass% B203 and 51-79 mass % SiO2. This barrier rib material consists of powdery glass and the powdery filler.
