    Abstract: PROBLEM TO BE SOLVED: To provide an electron emitting element capable of improving an amount of electron emission since a thin electrode can be thinned down to a moderate thickness. SOLUTION: This electron emitting element 1 includes an electron accelerating layer 4 between an electrode substrate 2 and a thin film electrode 3, and the electron accelerating layer 4 contains an insulator particulate 5 and at least either one of a conductive particulate 6 having an average particle diameter smaller than that of the insulator particulate 5 or a basic dispersant 60. The surface roughness of the electron accelerating layer 4 is not more than 0.2 μm in centerline average roughness (Ra), and the layer thickness of the thin electrode 3 is not more than 100 nm.

    Abstract: PROBLEM TO BE SOLVED: To further increase the efficiency and output of the emission of electrons, and to increase drive speed in a dielectric film type electron emitting element. SOLUTION: The electron emitting element 10 comprises an emitter 12; a first electrode 14; and a second electrode 16. The emitter 12 is a thin layer made of a polycrystalline substance of a dielectric material. The dielectric material for composing the emitter 12 is made of a material having a high mechanical quality coefficient (Qm value). More specifically, the Qm value of the dielectric material has a value that is higher than that of the so-called low-Qm material (a material having a Qm value of 100 or smaller). The Qm value of the dielectric material is preferably equal to or higher than 300, and is more preferably equal to or higher than 500. COPYRIGHT: (C)2007,JPO&INPIT
