Abstract:
1. 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 an arithmetic mean deviation of the profile of the metal back in said second region is larger than the arithmetic mean deviation of the profile of the metal back in said first region.
