Electron emitting device, electron source, image forming apparatus and producing methods of them










Image Number 3 for United States Patent #6492769.

In an electron emitting device, an electron source and an image forming apparatus making use of it, and producing methods of them, an organic film is present on a pair of conductive films forming the electron emitting device. This organic film is placed in an area on the conductive films. This prevents occurrence of leak paths between the conductive films, which used to occur because of change of the organic film on the substrate into a conductor where the organic film existed on the substrate outside the area of the conductive films, and prevents decrease in electron emission efficiency.
