Image display apparatus having ion pump and electron-emitting devices in communication via mesh or stripe shaped member

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.
