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.
