Abstract
The present invention provides an electron emitting element which has good energy efficiency and which is capable of controlling a value of current flowing in an electron acceleration layer and an amount of emitted electrons by adjusting a resistance value of the electron acceleration layer and an amount of generated ballistic electrons. An electron emitting elementincludes an electron acceleration layerincluding a fine particle layer containing insulating fine particles. In the electron emitting element
