Image display apparatus having first and second regions with respective luminances

An image display apparatus comprising a rear plate and a face plate facing the rear plate;

• wherein
• said rear plate includes an electron-emitting device;
• said face plate includes a light-emitting body which emits light by electron irradiated from said electron-emitting device, and a metal back arranged between said electron-emitting device and said light-emitting body, said light-emitting body including a first region in which a luminance with respect to a maximum value of a luminance in the light-emitting body is greater than or equal to 50% and a second region in which a luminance with respect to a maximum value of a luminance in the light-emitting body is less than 50%;
• and
• a ratio of an area of the metal back covering said second region with respect to an area of said second region is smaller than a ratio of an area of the metal back covering said first region with respect to an area of said first region.
