PROBLEM TO BE SOLVED: To enable an image display device to have display of high brightness and high definition through restraint of discharge generated between substrates, and reduction of cases of destruction of electron sources and a phosphor screen as well as of deterioration of light-emitting characteristics. SOLUTION: The image display device has a smoothing layer 36 stably and firmly fixing phosphor layers 32, 33, 34 on a second substrate 3 and smoothing their surfaces, a metal back layer 37 reflecting light output by the phosphor layers toward a given direction of the second substrate, and a material 38 denaturing the metal back layer into electrically discontinuous characteristics at each specific area connected with the number or an alignment of electron beam sources fitted to the first substrate 2. The material 38 is integrated with the metal back layer 37 at a prescribed temperature. COPYRIGHT: (C)2006,JPO&NCIPI
