Patent ID: 7511425

Claim:
An image display apparatus, comprising: a vacuum container formed of at least an electron source substrate on which multiple electron-emitting devices are arranged, and an image forming substrate which is arranged so as to be opposite to the electron source substrate and which has a phosphor film and an anode electrode film; (a) an ion pump having an ion pump casing and magnetic field forming means, the ion pump casing being connected with the vacuum container through a communicating path arranged on at least one of the electron source substrate and the image forming substrate to maintain a pressure inside the ion pump casing at a reduced pressure; and (b) a first magnetic shielding member arranged in a space where the ion pump and the electron-emitting devices are in communication with each other, wherein: the first magnetic shielding member allows a gas to flow between the vacuum container and the ion pump casing, the first magnetic shielding member has one or more flowing through holes, the first magnetic shielding member has one of a mesh shaped member and a stripe shaped member in the space, through which the ion pump and the electron-emitting devices are in communication with each other, and the one of the mesh shaped member and the stripe shaped member allows a gas to flow therethrough.
