To provide an electron emitting element capable of suppressing signal distortion to prevent screen quality deterioration due to the signal distortion.

The present invention relates to an electron emitting element further including an extra electrode having various functions in addition to electrodes contributing to electron emission. The electron emitting element includes first and second bases disposed opposite to each other, cathode and gate electrodes disposed on the first base via an insulating layer in an effective electron emission region provided on the first base, an electron emission source formed so as to electrically contact with the cathode electrode, at least one dummy electrode positioned out of the effective electron emission region, at least one anode electrode formed on the second base, and a fluorescent layer formed on one surface of the anode electrode.
