A front substrate of an image display comprises a phosphor screen (6), a metal back layer which is formed on the phosphor screen and has a plurality of divided regions (7a) that are separated from one another, a common electrode (24) for applying an voltage to the metal back layer, and a plurality of connection resistors (30) for electrically connecting the respective divided regions of the metal back layer with the common electrode. A plurality of electron- emitting devices are arranged on a back substrate (1) which is arranged opposite to the front panel for discharging electrons toward the phosphor screen. The common electrode is covered with a coating member (32) which has a higher sheet resistance than the connecting resistors.
