Title: Image display apparatus having accelerating electrode with uneven thickness

Abstract: An image display apparatus includes a face plate having a phosphor and an accelerating electrode laminated on the phosphor, and a rear plate having an electron-emitting device emitting an electron to a partial region of the phosphor. An average thickness of the accelerating electrode laminated on the phosphor of a non-irradiation region not to be subjected to an irradiation with the electron emitted from the electron-emitting device, is larger than an average thickness of the accelerating electrode laminated on the phosphor of an irradiation region to be subjected to the irradiation with the electron emitted from the electron-emitting device.
