Image display device and spacer

Abstract

To provide a spacer, which is unlikely to degrade due to heating received during manufacture process of an image display device, and an image display device equipped with the spacer. An image display device includes: a cathode substrate including an electron source; an anode substrate including a fluorescent substance that emits light upon receiving electrons emitted from the electron source; and a spacer that is disposed between the cathode substrate and the anode substrate and supports the both substrates, wherein the spacer comprises the one having a film composed of a composite metal oxide on a side surface of a glass base material, the composite metal oxide being composed of a solid solution of a metal oxide having a semiconductor-like electrical conductivity and a metal oxide having an insulator-like electrical conductivity. The spacer equipped with this composite metal oxide film has less degradation, such as that a glass composition volatilizes, even if heated during the manufacture process of an image display device, and provides an excellent image.
