Abstract
The present invention provides an electron emitting element, comprising: a first electrode; an insulating fine particle layer formed on the first electrode and composed of insulating fine particles; and a second electrode formed on the insulating fine particle layer, wherein the insulating fine particles are monodisperse fine particles, and when voltage is applied between the first electrode and the second electrode, electrons are discharged from the first electrode into the insulating fine particle layer and accelerated through the insulating fine particle layer to be emitted from the second electrode.
