Abstract
An image display device includes a first substrate which has a phosphor surface, and a second substrate which is opposed to the first substrate with a gap and has a plurality of electron sources. A plurality of spacers are arranged between the first substrate and the second substrate and support an atmospheric load acting on the first and second substrates. Each of the spacers has distal end portions at the first and second substrates, respectively. The distal end portions of each spacer are impregnated with electrically conductive material and constitute conductivity-imparting portions.
