PROBLEM TO BE SOLVED: To provide an image display device like an FED (field emission display) prevented from breakage and deterioration of an electron emitting element or a fluorescent surface by improving the dielectric strength, attaining a display with high brightness and high quality. SOLUTION: The fluorescent surface of the image display device has a light absorbing layer and a phosphor layer, a metal back layer formed on the phosphor layer having a dividing part, a covering layer with high resistance formed on the dividing part of the metal back layer so as to stride over the metal back layers at both sides, a heat resistant fine particle layer formed on the covering layer, and a getter layer formed on the metal back layer divided by the heat resistant fine particle layer.
