Abstract

PURPOSE: To prevent a blister, exfoliation, etc. of the metal back film and a lowering of pressure-proof in the tube, by means of constructing a metal back film on the surfaces after constructing a granulated powder on an organic flim.
CONSTITUTION: In the inner face of a face panel 11, are successively constructed a phosphor film 12 and an organic film 13, consisting of polymethacrylate, thereafter, a small amount of granulated powder 14, consisting of ammonium carbonate, is dispersedly made sticking on to the organic film 13. In this process, a small protrusion is constructed on the organic film 13. And then, on the film 13 is evaporated a metal back film 15, consisting of likely aluminums, with the panel 11 heated after evaporation and the organic film 13 made firing and removed, and the process of this firing also decomposes and removes the granulated powder. In this way, a blister, exfoliation, etc. of the metal back film can be prevented.
