ABSTRACT:
An electron beam apparatus in which a spacer having a high-resistance film coating a surface of a base material is inserted between a rear plate having electron emitting elements and row-direction wires, and a faceplate having a metal back. The row-direction wires and the metal back are electrically connected via the high-resistance film. An electric field near an electron emitting element near the spacer is maintained to substantially constant irrespective of the positional relationship between the spacer and the electron emitting element near the spacer. When a sheet resistance value of the high-resistance film on a first facing surface of the spacer that faces a row-direction wire is represented by R1, and a sheet resistance value of the high-resistance film on a side surface adjacent to the electron emitting element is represented by R2, R2/R1is 10 to 200.
