PROBLEM TO BE SOLVED: To provide an enclosure for an image display device less in brightness reduction or life shortening, and sufficient in getter effect, by realizing an adhesion process at a temperature about 400 deg.C or below required at the minimum for a frit adhesion (sealing) process. SOLUTION: A rear plate 2 and a face plate 4 are joined respectively at joining parts to an outer frame 3 through polymer thermoplastic adhesives 9, 14 containing a polyphenyl compound. As the adhesives, a polymer thermoplastic adhesive containing polyether, polysulfone or polyether ketone, of the like is named. Especially a polymer thermoplastic sheet-shaped adhesive mainly composed of polyether ketone is used and heated to 330 deg.C or higher, to soften and crimp the adhesive, and the adhesive is hardened and bonded in a temperature-lowering process. Polyether ketone is preferable compared with other adhesives, especially from the viewpoint of a small quantity of emission gas in a vacuum baking process.
