Abstract: In an image display apparatus including: an electron source; a target having a phosphor and an anode electrode, the target emits light for display by being illuminated with electrons from the electron source; and an intermediate electrode disposed in the midpoint between the electron source and the target, the intermediate electrode is applied with a potential greater than that applied to the anode electrode. Thereby, halation caused by back scattering electrons reentering a phosphor is reduced.

Abstract: In an image forming apparatus in which a rear plate having electron-emitting devices and a face plate having light emitting members, a black matrix, and metal back electrodes are arranged so as to face each other, an influence on the electron-emitting devices by a discharge between the rear plate and the face plate is reduced, thereby realizing high durability and a long life. Strip shaped resistors which are parallel with the Y direction, phosphor, and a black matrix to shield an area between adjacent phosphor against the light are arranged to scanning wirings which are parallel with the X direction. Further, metal back electrodes which are electrically connected to the strip shaped resistors through the black matrix and cover the strip shaped resistors and phosphor are arranged in the X direction, thereby constructing the face plate.
