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.

An image display apparatus includes a rear plate including electron-emitting devices, a face plate including an anode electrode, a voltage applying unit configured to apply a voltage to the anode electrode, a switching unit configured to switch between a display state of displaying an image and a non-display state of displaying no image, and a timing unit. The timing unit measures a non-display time, which is an amount of time that the switching unit allows the non-display state to continue. After the timing unit has measured a certain non-display time, the voltage applying unit applies, to the anode electrode, a second voltage lower than a first voltage to be applied in the display state, to enable the electron-emitting devices to emit electrons.
