Abstract:
An electron emitting element of the present invention includes an electron acceleration layer between an electrode substrate and a thin-film electrode. The electron acceleration layer includes a binder component in which insulating fine particles and conductive fine particles are dispersed. Therefore, the electron emitting element of the present invention is capable of preventing degradation of the electron acceleration layer and can efficiently and steadily emit electrons not only in vacuum but also under the atmospheric pressure. Further, the electron emitting element of the present invention can be formed so as to have an improved mechanical strength.
