Abstract
An electron emission element includes a substrate, a cathode electrode formed on the substrate, an anode electrode disposed so as to be opposed to the cathode electrode, an electron emission member disposed on the cathode electrode, a control electrode disposed between the cathode electrode and the anode electrode, and an insulating layer. The electron emission member includes a first member having a hole and a second member filling the hole, wherein the second member is more likely to emit electrons than the first member.
