Patent ID: 7326097

Claim:
A method of manufacturing an image displaying apparatus, comprising the steps of: a: disposing, on a support, a substrate on which an electrical conductor and a wiring connected to the conductor are formed; disposing, on the substrate, a container so that the container covers the electrical conductor on the substrate except for a part of the wiring; setting, into a desired atmosphere, a hermetic atmosphere formed between the container and the substrate; and applying a voltage to the conductor through the part of wiring, to form an electron-emitting device at a part of the conductor, and to form an electron source substrate; b: disposing, within a vacuum atmosphere, one or both of the electron source substrate and a phosphor substrate on which phosphor emitting light by the electron-emitting device is arranged; c: carrying under the vacuum atmosphere one or both of the electron source substrate and the phosphor substrate into the vacuum atmosphere in a gettering process chamber, and subjecting to a gettering process one or both of the substrates carried therein; and d: carrying under the vacuum atmosphere the electron source substrate and the phosphor substrate into a vacuum atmosphere in a seal-bonding process chamber, and subjecting to heat seal-bonding the substrates in an opposing state, wherein the gettering process chamber in step c is evacuated into a vacuum level higher than a vacuum level of the vacuum atmosphere in step b.
