To provide an image display apparatus with an anti-atmospheric pressure measure taken in a display panel by placing a spacer between a face plate and a rear plate without affecting image quality.

The image display apparatus has a spacer that is disposed in contact with a first substrate and a second substrate in a vacuum container and composed of a base material and a film having a resistance higher than a first electrode or a second electrode covering the base material. The apparatus satisfies 0.3S1≤s1≤0.003A or 0.3S2≤s2≤0.003A, where A is an inner cross sectional area of the vacuum container taken along a plane parallel with the first substrate, S1 is a total area of an end portion of the spacer that is close to and faces toward the first substrate, S2 is a total area of an end portion of the spacer that is close to and faces toward the second substrate, s1 is an actual contact area between the spacer and the first electrode, and s2 is an actual contact area between the spacer and the second electrode.
