Patent ID: 8378565

Claim:
An electron emitting element comprising: an electrode substrate and a thin-film electrode, which are provided so as to face each other; and an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode, the electron emitting element (i) accelerating electrons in the electron acceleration layer at a time when a voltage is applied between the electrode substrate and the thin-film electrode and (ii) emitting the electrons from the thin-film electrode, the electron acceleration layer including a fine particle layer containing insulating fine particles to which fine particle layer a single material or a mixed material that facilitates electricity flow in a thickness direction of the fine particle layer is applied, the electron acceleration layer including a conductive path formed therein in advance such that the conductive path runs through the electron acceleration layer in a thickness direction of the electron acceleration layer, the conductive path having an exit serving as an electron emitting section via which the electrons are supplied to the thin-film electrode, the single material or the mixed material being conductive fine particles, the conductive fine particles being deposited on a surface of the fine particle layer so as to form a deposition, and the deposition of the conductive fine particles having a physical recess serving as the electron emitting section.
