摘要： A field emission element including an electrode structure made of a thin film exhibiting increased adhesive strength. A thin film of niobium nitride (NbN) is formed on a glass substrate by sputtering or the like. The NbN film exhibits increased adhesive strength to a degree sufficient to prevent etching for formation of the film into electrodes from causing peeling of the film.

摘要： A field emission cathode capable of reducing an operation voltage and substantially preventing damage of an emitter. An emitter is provided on a substrate. The emitter includes a base and a plurality of rectangular tips projecting from the base. A gate is arranged in a recess formed on the substrate so as to be in proximity to the emitter. A width a of the tips of the emitter and an interval b between the tips are defined to satisfy a relationship of b/a=2. This permits an electric field strength applied to the tips of the emitter to be substantially increased as compared in a conventional field emission cathode of b/a.ltoreq.1, resulting in an operation voltage being reduced and a sufficient amount of emitter current being produced.

摘要： An electron feed structure for a flat-type luminous device capable of permitting electron emitted from an electrons source to be uniformly fed throughout a display section. The electron feed structure includes an electron flow guide constituted by an inner guide electrode of a high voltage and an outer guide electrode of a low voltage, so that an electric field of a high voltage and that of a low voltage may be alternately formed to form electrostatic lenses in the guide, to thereby effectively prevent the function of the electron flow guide from being deteriorated. A guide voltage applied to each of the electrode segments of the inner guide electrode is rendered constant and a guide voltage applied to each of the electrode segments of the outer guide electrode is likewise rendered constant, to thereby cause the correlation between the guide voltage and a deflection voltage applied to the electron flow guide to be uniform irrespective of a position within the electron flow guide, resulting in electrons emitted from the electron source being drawn out under the same conditions.
