PROBLEM TO BE SOLVED: To maintain a uniform brightness over a long period of time in an image display apparatus in which a rear plate 7 equipped with a plurality of electron emitting elements 8 equipped with a pair of electrode and a conductive film having an electron emitting part desposed therebetween, and a face plate 11 provided with a fluorescent body 12 displaying an image by being irradiated by electrons from the electron emitting element 8 and a metal back 13 exposing on the surface of the fluorescent body 12 are facing each other. SOLUTION: A film of a metal or a metal compound material, which is the same metal or metal compound material as that constituting the metal back 13, is provided in a thickness≥0.2 nm and≤4.5 nm in an adjacent range of the electron emitting part of each electron emitting element 8.
