An image display apparatus is provided with a vacuum chamber consisting of an electron source substrate and an image display substrate, and an ion pump which is attached to an electron-emitting substrate or the image display substrate and exhausts air from the vacuum chamber by the action of a magnet, wherein the magnet is attached and fixed to the substrate to which the ion pump has been attached. Thereby, the image display apparatus prevents the magnet from applying an excessive force to the ion pump by its weight, and acquires a stable structure without causing a vacuum leak.

Image display device having an ion pump with reduced leakage

In an image display apparatus composed of a vacuum container having an electron source composed of multiple electron-emitting devices and a phosphor film that is irradiated with an electron from the electron source to emit light for display, an ion pump for exhausting the vacuum container through a communicating path by virtue of an action of a magnetism forming portion is arranged. A magnetic shielding member is arranged in a space where the ion pump and the electron-emitting devices are in communication with each other, whereby an influence of a magnetic field generated by the magnetism forming portion on the trajectory of an electron emitted from any one of the electron-emitting devices and display luminance unevenness incidental to the influence are removed.

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

In an image display device having in an airtight container an electron source and an image display member that receives electrons from the electron source, an evaporating getter and a non-evaporating getter are stacked in the airtight container. This makes it possible to maintain the vacuum level in the airtight container. The image display device thus obtains a prolonged life and a stable display operation.
