  • Patent number: 5872541
    Abstract: A display device consisting of an electron-emitting device which is a laminate of an insulating layer and a pair of opposing electrodes formed on a planar substrate. A portion of the insulating layer is between the electrodes and a portion containing an electron emitting region in between one electrode and the substrate. Electrons are emitted from the electron emission region by a voltage to the electrodes, thereby stimulating a phosphorous to emitting light.

  • Patent number: 5017988
    Abstract: An image reading device has an entrance window provided in a substrate for receiving the light illuminating an information bearing member bearing information to be read. A photosensor is provided on the substrate for receiving the light that has entered through the entrance window and has been reflected by the information bearing member. Further, a protective layer is formed on the photosensor opposite to the substrate, in order to maintain a constant distance between the information bearing member and the photosensor, and has a multi-layer structure of separate functions, comprising a first layer of a first function at the side of the photosensor, and a second layer of another function different from the first function.
