Abstract: An electron source includes a plurality of electron emitting devices arranged in a matrix, and an image forming apparatus uses the electron source. Each of the row-direction wirings of the electron source is selected sequentially and a scan signal is applied thereto, and in synchronization of the scan signal, a modulation signal corresponding to an image signal is applied to the column-direction wiring. The row- and column-direction wirings of the electron source are connected by a connection cable having an impedance substantially equal to a characteristic impedance of a driving area of the electron source, thereby preventing signal ringing in the inputted scan signals and modulation signals. In place of the connection cable, a damping resistance having a resistance value substantially equal to the characteristic impedance may be connected in serial to each of the column- or row-direction wirings, to prevent the signal ringing.

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.
