A method and an apparatus of manufacturing an image displaying apparatus
having an electron source substrate and a phosphor substrate. The electron
source substrate is provided with an electron emitting element formed by
covering with a container and by applying a voltage to an electronic
conductor on the substrate. While, the phosphor substrate is provided with
a phosphor thereon. The substrates are subjected to a getter processing
and to a seal bonding process under a vacuum condition through a
processing chamber, to complete an image forming apparatus. An improvement
resides in miniaturizing and simplifying operation, and in greater
manufacture speed and mass production.
