ABSTRACT:
An electron emission device is provided which has sufficient on/off characteristics and is capable of efficiently emitting electrons with a low voltage. An electron emission device includes a substrate, a cathode electrode, a gate electrode, which are arranged on the substrate, an insulation layer covering the surface of the cathode electrode, and a dipole layer formed by terminating the surface of the insulation layer with hydrogen.
