    Abstract: In an electron-emitting device including, between electrodes, an electroconductive film having an electron emitting region, the electroconductive film has a film formed in the electron emitting region and made primarily of a material having the higher melting point than that of a material of the electroconductive film. Alternatively, the electroconductive film has a film formed in the electron emitting region and made primarily of a material having a higher temperature, at which the material develops a vapor pressure of 1.3 x 10 Pa, than that of a material of the electroconductive film. A manufacture method of an electron-emitting device includes a step of forming a film made primarily of a metal in the electron emitting region of the electroconductive film. The electron-emitting device has stable characteristics and improved efficiency of electron emission. An image-forming apparatus comprising the electron-emitting devices has high luminance and excellent stability in operation.

    Abstract: A method of manufacturing an electron emitting device (104) of the type having, on a substrate 1, an electroconductive thin film (3) with an electron-emitting region (2), connected to respective electrodes (4,5). The electroconductive film (3) is formed by spraying through a nozzle (33;131) a solution containing component elements of the electroconductive thin film (3) which is to be formed. Spraying is performed whilst an electrical potential difference (V) is produced between the electrodes (4,5), between the nozzle (131) and the substrate (1), or both. The effect is to improve adherence of the film (3) to the substrate (1) or substrate and electrodes (1,4,5). This method may be extended to the manufacture of an electron source (1,102-104) having an array of electron-emitting devices (104).

    Abstract: An electron-emitting device (1-5) having a pair of electrodes (2,3), an electroconductive film (4) arranged between the electrodes (2,3), and a gap formed in the electroconductive film, defining an electron-emitting region (5), is exposed to an atmosphere containing one or more than one organic substance and a gas having a composition expressed by the general formula XY (where both X and Y represent a hydrogen or a halogen atom) while a voltage, preferably a bipolar pulse voltage, is applied across the electrodes (2,3).

    Abstract: A method for producing an image-forming apparatus, the image-forming apparatus comprises a container, an electron-emitting device disposed in the container and has an electron-emitting section between a pair of electrodes, the electron-emitting device being adapted to emit electrons with application of a voltage between the pair of electrodes, and an image-forming member for forming an image by irradiation of the electrons emitted from the electron-emitting device, the production method having a step of irradiating the image-forming member with electrons emitted from the electron-emitting device, wherein the electrons to irradiate the image-forming member are electrons emitted by applying to the electron-emitting device the voltage of an opposite polarity to that of a voltage applied between the pair of electrodes of the electron-emitting device during driving for image formation of the image-forming apparatus.

A manufacture method of an electron-emitting device includes a step of forming a film made primarily of a metal in the electron emitting region of the electroconductive film. The electron-emitting device has stable characteristics and improved efficiency of electron emission.
