Methods of manufacturing electron-emitting device, electron source, and image-forming apparatus |
摘要 |
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.
