Patent ID: 7554256

Claim:
An image display apparatus, comprising: a face plate including a light-emitting member for emitting light by irradiation with an electron beam, a first electroconductive film stacked on the light-emitting member, and a second electroconductive film which is distant from an outer periphery of the first electroconductive film and is arranged to surround the outer periphery of the first electroconductive film; and a rear plate on which an electron-emitting device is located, wherein the second electroconductive film has an end portion opposed to the outer periphery of the first electroconductive film, at least a part of an edge of the end portion is covered with a dielectric film, and when an interval between the face plate and the rear plate is given by H [μm], the dielectric film covers the second electroconductive film over a length given by L [μm] from the edge of the second electroconductive film in a direction distant from the first electroconductive film, where L≦ 0.025 ×H+ 15 is satisfied.
