    Abstract: PROBLEM TO BE SOLVED: To provide an activation method which increases the number of emission sites relative to a conventional activation method, in a manufacturing method of an electron emission element formed of fibrous carbon such as a carbon nanotube. SOLUTION: A cathode board 1 and an anode board 2 are arranged by facing each other in a depressurized atmosphere with an activation gas introduced therein, and a reverse bias voltage is applied to the cathode conductor 12 and an anode conductor 22. That is to say, a positive voltage is applied to the cathode conductor 12, and a negative voltage is applied to the anode conductor 22. A surface of a carbon layer 13 formed by applying and drying paste containing fibrous carbon and carbon impurities is roughened (destroyed), and carbon fibers 141 and 142 are exposed. Then, the length of the long carbon fiber 141 of the cathode board 1 in Fig. 1(c) is adjusted to a value equivalent to that of the carbon fiber 142 by removing a tip thereof by an equalization method.

    Abstract: PROBLEM TO BE SOLVED: To provide an electron source which is a thin film type electron source having a lower electrode and an upper electrode and an electron acceleration layer comprising an insulator or a semiconductor between them starting a diode current at lower threshold voltage than in the prior art and capable of securing a diode current required for electron emission even at low voltage, and to realize an image display device having a long service life and low power.
    SOLUTION: It is realized by using noble metal of a platinum group (8 group) or an Ib group containing alkali metal oxide, alkaline earth metal compound and a transition-metal compound of 3 to 7 group from an interface with the electron acceleration layer to the surface or their laminated film, mixed film or alloy film as the upper electrode.
