Title: Plasma display panel and manufacturing method therefor
Inventor: JO KEISUKE
IPC: H01J11/42
Filed: 2001-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a plasma display panel which can raise the purity of the inert gas within a discharge space, especially around a phosphor while maintaining its high production efficiency and high shape precision, and to provide a manufacturing method therefor.
