Abstract: In an image display apparatus, by providing an insulating member which covers an electroconductive member existing in a region out of an electron beam emitting region, an unnecessary discharge from the electroconductive member is suppressed and a damage due to the discharge is prevented, thereby realizing a long life of the apparatus.

Abstract: In a producing method for an electron beam emitting device, a position of a stray emission source constituting an unnecessary electron emitting part on a cathode substrate is detected, and an energy is locally applied to the detected position thereby eliminating the stray emission source, thereby providing an excellent electron beam apparatus without a deterioration in a constituent member or a trouble by an accidental discharge.
