    • The first basic structure of the electron emission element of the present invention, includes at least two electrodes disposed in a horizontal direction at a predetermined interval, and a plurality of electron emission portions made of a particle or an aggregate of the particles dispersively disposed between the electrodes. On the other hand, the second basic structure of the electron emission element of the present invention includes at least two electrodes disposed at a predetermined interval, a conductive layer disposed between the electrodes so as to be electrically connected thereto, and a plurality of electron emission portions made of a particle or an aggregate of the particles dispersively disposed on the surface of the conductive layer between the electrodes. According to these structures, an electron emission element with high stability can be obtained, in which emissions can be emitted efficiently and uniformly even in the absence of a bias voltage (electric field) from outside in an output (emission) direction of the electrons, by utilizing a transverse electric field generated between the electrodes disposed in a horizontal direction at a predetermined interval or an in-plane electric current flowing through the conductive layer disposed between the electrodes.
