Abstract

PURPOSE: To uniformalize an electron emission distribution by broadly distributing the thick part for low-resistance assuring and the thin part for electron actual emission in a coexisting condition in the electron emission region part in a metal layer.
CONSTITUTION: An electron emission element is composed of the conductive material 12 formed on an insulation substrate 11, the insulation body layer 13 formed on the material 12, and the metal layer 14 formed on the layer 13. Many metal layers 14' having a belt-state are parallelly formed in the electron emission region 15 in the layer 14, and a layer 13 surface is exposed between each layer 14'. The layer 14' has the shape having a flat top part 14'a and a tilted edge part 14'b. The part with the part 14'a as the center is the thick part for low-resistance assuring, and the part with the foot of the part 14'b as the center is the thin part for electron emission. The part 14'b coexists with the part 14'a and is broadly distributed in the region 15. When voltage is applied between the material 12 and the layer 14, a strong electric field is generated, and electrons are broadly emitted from the whole area of the region 15.
