    Abstract: In a manufacture method of an electron-emitting device in which an electro-conductive film having an electron-emitting region is provided between electrodes disposed on a substrate, a step of forming the electron-emitting region comprises a step of forming a structural latent image in the electro-conductive film, and a step of developing the structural latent image. An electron source comprising a plurality of electron-emitting devices arrayed on a substrate, and an image-forming apparatus in combination of the electron source and an image-forming member are manufactured by using the electron-emitting devices manufactured by the above method. The position and shape of an electron-emitting region of each electron-emitting device can be controlled so as to achieve uniform device characteristics, resulting less variations in the amount of emitted electrons between the electron-emitting devices and in the brightness of pictures. Also, the need of flowing.a great current for formation of the electron-emitting region is eliminated and hence the current capacity of wiring can be reduced.

    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.

    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).
