METHOD OF MANUFACTURING GAS DISCHARGE PANEL, AND GAS DISCHARGE PANEL

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a gas discharge panel capable of obtaining the gas discharge panel of high quality by avoiding a malfunction due to the local heating of the panel in a chip tube unsealing process. SOLUTION: In a chip tube unsealing process, a cylindrical heat insulating material 9 is provided as a calorie reducing part between a heating part 8 and a back board 2, and most of the radiation heat transmitted from the heating part 8 to the back board 2 is cut by the heat insulating material 9 so as to remarkably reduce the calorie to be transmitted to the back board 2.
