A front substrate of an image display device comprises a phosphor screen, a metal back layer lapped on the phosphor screen and having a plurality of divided regions spaced from one another, a common electrode which applies voltage to the metal back layer, and a plurality of connecting resistors which connect the common electrode and the plurality of divided regions of the metal back layer. A plurality of electron emitting elements which emit electrons toward the phosphor screen are arranged on a rear substrate opposed to the front substrate. The common electrode is covered by a coat member having a sheet resistance higher than that of the connecting resistors.
