Patent ID: 7612494

Claim:
An image display apparatus comprising: 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, wherein the accelerating electrode includes a first metal thin film laminated on the phosphor and a second metal thin film laminated on a part of the first metal thin film positioned on a non-irradiation region which is not to be subjected to an irradiation with the electron emitted from the electron-emitting device, so that an average thickness of the accelerating electrode of the non-irradiation region is larger than an average thickness of the accelerating electrode of an irradiation region to be subjected to the irradiation with the electron emitted from the electron-emitting device, wherein an average thickness of a portion comprising the first metal thin film and the second metal thin film that is positioned on the non-irradiation region of the accelerating electrode is equal to or more than 300 nm, and wherein the irradiation region and the non-irradiation region are formed in the phosphor.
