Image display apparatus provided with an ion pump assembly arranged within an external container

An image display apparatus, comprising:

• a vacuum container which includes an electron source and an anode electrode opposed to the electron source and in which a pressure is maintained at a reduced pressure;
• an anode power source for applying a voltage to the anode electrode;
• and
• an ion pump arranged so as to communicate through the vacuum container, wherein:
• the ion pump comprises an ion pump container composed of a non-electroconductive material, an ion pump cathode and an ion pump anode, the ion pump cathode and the ion pump anode being disposed in the ion pump container;
• and
• an electroconductive film of which potential is regulated is formed on an internal surface of the ion pump container, and the internal surface of the ion pump container on which the electroconductive film is formed surrounds the ion pump cathode and the ion pump anode.
