Abstract
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.
