    Abstract: An electron source comprises a plurality of electron-emitting devices and a drive means for driving the devices. The drive means applies a voltage above a threshold level to selected ones of the plurality of electron-emitting devices according to an image signal to cause the selected devices to emit electrons. The drive means also applies a voltage pulse for bringing the plurality of electron-emitting devices into a high resistance state. The voltage pulse for bringing into a high resistance state has a polarity reverse to that of the voltage for causing electron emission and has a voltage rising rate of greater than 10V/sec.

    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: 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: 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).
