Abstract
Provided is an image display apparatus, including: a vacuum container which includes an electron source and an anode electrode opposed to the electron source; and an ion pump arranged so as to communicate through the vacuum container, in which: an ion pump container is composed of a non-electroconductive material; and an electroconductive film is formed on an external surface of the vacuum container on a side on which the ion pump container is mounted or on an internal surface of the ion pump container. The image display apparatus achieves: a reduction in weight of the ion pump; an improvement in compatibility to the vacuum container; and the prevention of an adverse effect of discharge inside the ion pump on image display.
