FLAT PANEL DISPLAYING DEVICE

摘要

PROBLEM TO BE SOLVED: To enhance the efficiency of an evacuation process resulting in improvement of the production efficiency or the like of a flat panel displaying device by controlling the crystallinity of a crystalline glass tablet and making proper the reaction of the tablet and a glass substrate (or the crystalline glass tablet and an evacuation tube) in order to elevate the temperature of the evacuation process while securing the sealing strength between the glass substrate and the evacuation tube in sealing thereof using the crystalline glass tablet. SOLUTION: In the flat panel displaying device in which the glass substrate and the evacuation tube are sealed by the crystalline glass tablet, the average reaction depth of the glass substrate at a sealing region is 0.05-2.5μm.
