摘要： An electron-emitting device in which the specific capacitance and the drive voltage are reduced, and which is capable of obtaining a finer electron beam by controlling the trajectory of emitted electrons. An electron-emitting portion of an electron-emitting member is positioned between the height of a gate and the height of an anode. When the distance between the gate and a cathode is d; the potential difference at driving the device is V1; the distance between the anode and the substrate is H; and the potential difference between the anode and the cathode is V2, then the electric field E1=V1/d during driving is configured to be within the range from 1 to 50 times E2=V2/H.

摘要： A method of manufacturing an electron emission element, including forming common wire electrodes (signal lines) (4a, 4b) on a substrate (1) and forming electron emission units including fibrous material assemblies (6a, 6b) on the common wire electrodes (4a, 4b), respectively, for preventing abnormal discharge caused by an antistatic film (7) with no deterioration in characteristics of the electron emission element. The electrode forming is followed by forming resist patterns (40a, 40b) covering at least part of the common wire electrodes (4a, 4b) before the antistatic film is formed. Thereafter the resist patterns (40a, 40b) on the common wire electrodes (4a, 4b) are removed together with the antistatic film (7) before the electron emission unit is formed, so that the electron emission units made of the fibrous material assemblies (6a, 6b) are formed on the common wire electrodes (4a, 4b) from which the resist patterns (40a, 40b) have been removed.

摘要： In an electron-emitting device having an electron-emitting member containing carbon as a main component, and an extraction electrode arranged near the electron-emitting member, electrons can be emitted by substantially only a region of the electron-emitting member close to the extraction electrode. Brightness nonuniformity and abnormal lights-on errors are reduced in an image forming apparatus in which the electron-emitting devices are constituted into an electron. The electron-emitting threshold field of the electron-emitting member is set low at a portion close to the extraction electrode and high at a portion apart from the extraction electrode.
