| Abstract | An image display device comprises: a front substrate having a fluorescent member for displaying an image, and a metal back for covering the fluorescent member; a rear substrate having an electron emission element; and a support frame disposed between the front substrate and the rear substrate. In the image display device, a thickness of the metal back is 55 nm or more and 120 nm or less, and at least the metal back is covered with a getter. Thus, since the metal back of the front substrate is covered with the getter, a time-dependent deterioration of luminance is small and a lifetime is long even if a potential of the metal back is high. |
