Abstract
An electron beam generating device has at least one electron emitting element and at least one modulation electrode on a substrate. The modulation electrode may be provided on the same or reverse side of the substrate as or to the side bearing the electron emitting element. The electron emitting element is constituted of a lower potential electrode, a higher potential electrode and an electron emitting portion between the electrodes. The lower potential electrode has a different dimension than the higher potential electrode, or the substrate region bearing the electron emitting element has a different thickness than the other region, depending on the type of arrangement of the electron emitting element and the modulation electrode.
