  • Patent number: 7500897
    Abstract: In an image display device having in an airtight container an electron source and an image display member that receives electrons from the electron source, an evaporating getter and a non-evaporating getter are stacked in the airtight container. This makes it possible to maintain the vacuum level in the airtight container. The image display device thus obtains a prolonged life and a stable display operation.

  • Patent number: 7442405
    Abstract: A novel process for producing an electron source substrate is disclosed for formation of electron-emitting element at high efficiency with less shape irregularity. In the process, the region for electroconductive film formation is divided into plural subregions on which an electroconductive film is formed respectively. In forming the electroconductive film by application of plural liquids, the time interval between the application of the two drops is controlled to be larger than the time length necessary for suppressing the spreading of the succeedingly applied liquid within an allowable limit.

  • Patent number: 6784613
    Abstract: A non-evaporating getter maintains the adsorbability for the residual gases, and in addition, secures sufficient characteristics particularly even when it experiences a high-temperature and low-vacuum condition in the fabrication process of a display unit. The non-evaporating getter includes a substrate having no function as a getter and a polycrystalline film arranged on the substrate which film contains Ti as the main component and has a host of voids in the interior thereof. A non-evaporating getter is made by forming a polycrystalline film containing Ti as the main component on the concavo-convex surface of the substrate which substrate has concavities and convexities on a surface thereof and has no function as a getter.
