Abstract
An electron emitting element of the present invention includes: an electrode substrate; a thin-film electrode; and an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode, the electron acceleration layer including (i) conductive fine particles, (ii) insulating fine particles having an average particle diameter greater than an average particle diameter of the conductive fine particles, and (iii) a crystalline electron transport agent. The crystalline electron transport agent is crystallized in the acceleration layer.
