ABSTRACT:
An image display apparatus comprises an envelope internally provided with at least an electron emitting source, a fluorescent material member that emits light upon irradiation with an electron beam emitted from the electron emitting source and a getter that maintains the vacuum inside the envelope, and a vacuum exhaust tube that forms a vacuum inside the envelope, wherein the inside of the envelope is partitioned with a substrate into a first space having at least the electron emitting source and the fluorescent material member and a second space containing at least the getter, and the substrate has a path that communicates both the spaces.
