Envelope for display device and method for manufacturing same

摘要

A method of making an envelope for a display device is capable of permitting positioning and fixing of glass beads acting as spacers to be carried out with high precision and increased strength, respectively. Liquid for forming photoadhesive photosensitive film is applied to a substrate. The substrate is exposed to light through a mask to cause portions of the film on which glass beads are to be fixed to exhibit adhesion. Glass beads coated with glass frit of a low softening point are applied to the substrate and unnecessary glass beads other than those applied to the above-described portions of the film are removed. Subsequently, a casing is arranged on the substrate and calcination is carried out. This results in the photosensitive film volatilizing and the glass beads being adhered to both a flat plate and the substrate.
