Abstract:
1. An electron emitting element comprising: an electrode substrate; a thin-film electrode; and an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode, the electron emitting element (i) accelerating electrons between the electrode substrate and the thin-film electrode at a time when a voltage is applied between the electrode substrate and the thin-film electrode and (ii) emitting the electrons from the thin-film electrode, the electron acceleration layer including (a) conductive fine particles and (b) insulating fine particles whose average particle diameter is greater than that of the conductive fine particles, and where x (nm) is the average particle diameter of the insulating fine particles, and y (nm) is a thickness of the thin-film electrode.
