The present invention relates to an improved technique of an image display apparatus and a method for manufacturing the image display apparatus. The image display apparatus of the present invention is composed of a rear plate and a face plate disposed opposite to each other, the rear plate being equipped with a plurality of electron-emitting devices, each provided with a pair of electrodes and an electroconductive film including an electron-emitting region disposed between the electrodes, the face plate being equipped with a phosphor for displaying an image by being irradiated by electrons from the electron-emitting devices and a film exposed on a surface of the phosphor, the film comprising a metal or a metal compound material. The improved respects are that a film comprising the same metal or the same metal compound material as the metal or the metal compound material constituting the film exposed on the surface of the phosphor, the film formed on each of the electroconductive films of the plurality of electron-emitting devices to have a thickness in a range from 0.2 nm to 4.5 nm. Thereby, it is possible to provide an image display apparatus capable of keeping the homogeneity of brightness over a long period.
