In a field emission cold-cathode device, a cathode line or electrode is arranged on a glass substrate. An emitter is arranged on the cathode electrode and is formed of a conductive layer, a low-work-function material layer, and a tip layer stacked one on top of the other in this order. The emitter has a pyramid shape in which the tip layer has a sharp tip. The low-work-function material layer is made of a material having a work function of 4.0 eV or less. The tip layer is made of a material having a negative electron affinity and formed of granular bodies or linear bodies each having a diameter of 100 nm or less.

A field emission cathode which comprises an emitter provided with a sharp point for emission of electrons and a controlling gate electrode is composed of a supporting substrate, an emitter material layer formed of an emitter material, superposed on and attached fast to the supporting substrate, and provided with an emitter hole, an insulator layer so formed on the surface of the emitter material layer as to expose the tip part of the emitter projection therethrough, and an impurity diffusion layer formed on the surface of the insulator layer and enabled to function as an etching stopper layer. The method for the production of the field emission cathode comprises a step of forming a first hole pointed toward the leading end thereof on a first supporting substrate, a step of forming the impurity diffusion layer on the surface of the first supporting substrate, a step of forming the insulator layer on the surface of the impurity diffusion layer, a step of depositing an emitter material layer on the surface of the insulator layer including a hole while filling the hole with an emitter material thereby giving rise to a laminate, a step of integrally joining a second supporting substrate to the surface of the emitter material layer of the laminate, a step of removing by etching the first supporting substrate thereby exposing the surface of the impurity diffusion layer including the projection corresponding to the first hole, and a step of selectively removing the impurity diffusion layer and the insulator layer thereby exposing a tip of the projection of the emitter layer.

There is provided a field emission type display which is capable of suppressing deterioration of image quality which otherwise occurs due to stepwise cuts and to the increase of wiring resistance caused by a thin width of a cathode line and which causes less failures. The display includes a plurality of cathode lines having an equal line width within the pixel and is structurally based on a multiple gradation representing a scheme of controlling spatial gradation display by changing the number of field emission type emitters to be driven by changing the number of cathode lines to be selected.
