An electron-emitting device comprises a pair of electrodes and an electroconductive film arranged between the electrodes and including an electron-emitting region carrying a graphite film. The graphite film shows, in a Raman spectroscopic analysis using a laser light source with a wavelength of 514.5 nm and a spot diameter of 1μm, peaks of scattered light, of which 1) a peak (P2) located in the vicinity of 1,580 cm−1 is greater than a peak (P1) located in the vicinity of 1,335 cm−1 or 2) the half-width of a peak (P1) located in the vicinity of 1,335 cm−1 is not greater than 150 cm−1.
A method of manufacturing an electron-emitting device comprising a pair of electrodes and an electroconductive film arranged between the electrodes and including an electron-emitting region, comprising a step of applying a voltage to the electroconductive film containing a gap therein in an atmosphere containing one or more than one organic substances and a gas having a composition expressed by a general formula XY (where both X and Y represent hydrogen or a halogen atom).
A method of manufacturing an electron-emitting device comprising a pair of electrodes and an electroconductive film arranged between the electrodes and including an electron-emitting region, comprising a step of applying a voltage to the electroconductive film containing a gap therein, the voltage being a bipolar pulse voltage.
A method of manufacturing an electron-emitting device comprising a pair of electrodes and an electroconductive film arranged between the electrodes and including an electron-emitting region, comprising the steps of forming a graphite film on the electroconductive film including an electron-emitting region and removing any deposits other than the graphite film.
