Abstract: PROBLEM TO BE SOLVED: To properly install a getter by fixing the getter mounted in an airtight container by an inorganic high molecular compound or a substance derived from the inorganic high molecular compound. SOLUTION: An envelope 5 is formed by mutually adhering peripheral edge parts of a rear plate 2 supporting an electron source board 1 and a face plate 4 by upper and lower joint parts of a supporting frame 3 by using the frit glass. A NEG chip (non-evaporation-type getter) 9 is fixed to an upper wiring 102 with an inorganic adhesive. As the inorganic adhesive, a chemical reaction- type adhesive composed of a binding agent, a hardener and an aggregate is used. The chemical reaction-type adhesive is roughly categorized into a silicate adhesive, a phosphate adhesive and a colloidal silica adhesive. The NEG chip 9 is temporarily fixed by using the inorganic adhesive, and every board (the face plate 4 or the electron source board 1) at a NEG chip mounting side, is heated and baked to finally fix the NEG chip.

Abstract: PROBLEM TO BE SOLVED: To provide stable electron emitting characteristics of high efficiency by providing first and second carbon films on a substrate, providing first and second electrodes for electrically connecting to respective carbon films, applying voltage on the second electrode higher than that applied on the first electrode and containing a nitrogen in the carbon films to be connected. SOLUTION: This electron emitting part 5 consists of a second interval 6 formed on a part of a conductive film 4 and a carbon containing film (carbon film) 10 covering a substrate 1 in the second interval 6 and the conductive film 4 near the second interval 6. A voltage is applied on an element electrode 2 higher than that applied on an element electrode 3. By further applying a high voltage on an anode electrode, electrons are emitted from the electron emitting part 5 to the anode electrode. A nitrogen is contained in the carbon film 10 connected to the element electrode 2. By controlling the ratio of the number of nitrogen atoms to the number of carbon atoms (the number of nitrogen atoms/the number of carbon atoms) at 2/100 or more to 15/100 or under, driving stability with high efficiency is enhanced.
