摘要： PROBLEM TO BE SOLVED: To enable highly efficient electron emission with low voltage drive and to suppress dispersion of the amount of electron emission. SOLUTION: In this electron emission source, a cathode wiring 102 is formed on an insulating substrate 101 and a cathode electrode 103 is formed being joined to the cathode wiring 102. A carbon substance containing carbon nanotubes is attached on the paste-like cathode electrode 103. Many carbon nanotubes are oriented in the direction orthogonal to the cathode electrode 103 by drying the cathode electrode 103 in the condition that an electric field is applied between the cathode electrode 103 and an electric field applying electrode 502 attached on the substrate 501. The electron emission source is completed by forming a gate electrode, etc.

摘要： PROBLEM TO BE SOLVED: To enable highly efficient electron emission with low voltage drive. SOLUTION: In this electron emission source, a cathode wiring 102 is formed on an insulating substrate 101 and a paste-like cathode electrode 103 is formed being joined to the cathode wiring 102. A powder of a carbon substance containing carbon nanotubes is dispersed and attached on the cathode electrode 103. In a carbon nanotube 104, many carbon nanotubes exist in the direction orthogonal to the cathode electrode 103 or being oriented atilt in the direction close to the direction orthogonal to the cathode electrode 103. Unnecessary carbon nanotubes deposited on the insulating substrate 101 are removed by air blow, and then a gate electrode is formed. Consequently, the electron emission source is completed.

摘要： PROBLEM TO BE SOLVED: To feed drive power to a positive electrode for downsizing and lighting. SOLUTION: On a black matrix layer 6 on the inner face of a front plate 1 consisting an envelope 5, metal back layers are formed stripe-like at every row of picture elements 8. Separator electrodes 10 are connected in the row direction of the picture elements 8, and are separatedly disposed from other rows. Two piezoelectric transformers 31 are disposed on a black matrix layer between an upper row separator electrode 10a and a lower separator electrode 10b. The output 31a of one side piezoelectric transformer is wired to the upper separator electrode 10a, the output of the either piezoelectric transformer 31b is wired to the separator electrode 10b. In the inputs of the respective piezoelectric transformers 31a, 31b, wiring patterns are extracted from a part between the front plate 1 and a side plate 2, or from the back plate 3 of a low voltage side and are connected to a control circuit. The input of the piezoelectric transformers 31a, 31b is controlled by the control circuit, and the control of a drive power source input to an positive electrode 7 at every row of the picture elements 8 is conducted.

摘要： PROBLEM TO BE SOLVED: To reduce price, and allow efficient electron emission with low voltage drive by using carbon material having at least one of carbon nano-tube, Fullerence, nano-particles, nano-capsule, and carbon nano-horn. SOLUTION: An insulating substrate 101, a cathode conductor 102, and a paste-like carbon layer containing carbon nano-tube are laminated, then dried, and burned. By ribbing the carbon layer with a blade, emitters 301 where the carbon nano-tube is exposed from the wall portions 302 of the ribs are formed. Thereafter, by forming rib-like gate electrodes 404 an electron releasing source is completed.

摘要： PROBLEM TO BE SOLVED: To efficiently emit electrons with low-voltage drive by using a carbon material, having at least one of carbon nanotube, fullerene, nanoparticle, nanocapsule and carbon nanohorn. SOLUTION: A cathode conductor 102 and a paste-like carbon layer 201, including carbon nanotube, are laminated on an insulating substrate 1. A paper 301 is adhered to the carbon layer 210 and dried, so as to have the carbon layer 201 and the paper 301 unified. After peeling the surface part of the carbon layer 201 and the paper 301 from the carbon layer 201, the carbon layer 201 is burned to form an emitter. Thereafter, a gate electrode is formed so as to complete an electron emitting source.

摘要： PROBLEM TO BE SOLVED: To stabilize light emitting, miniaturize an ultraviolet ray source, and improve the uniformity in light emitting. SOLUTION: This ultraviolet ray source 1A has an anode substrate 6 having the translucent property, an opposing substrate 7 facing the anode substrate 6 across a predetermined interval, and a framelike side face plate 8 provided in an outer peripheral part between the anode substrate 6 and the opposing substrate 7 and has a boxlike envelope 2 whose inside is held in a vacuum condition. A phosphor layer 9 having a peak wavelength of 300 nm or more and 400 nm or less is formed into a predetermined light emitting pattern shape on an inner face of the anode substrate 6, and a metal back layer 10 is formed so as to cover the phosphor layer 9. An anode is conducted and connected with the metal back layer 10. A linear cathode 5 discharging electrons is stretched and provided in the envelope 2, and an acceleration control electrode 4 having a meshlike or slitlike opening part 4a on a surface facing the phosphor layer 9 is provided on an inner face of the opposing substrate 7. The electrons discharged from the cathode 5 are accelerated and controlled by the acceleration control electrode 4 and are emitted and plug into the phosphor layer 9 so that the phosphor layer 9 emits light.
