    Abstract: In an electron source comprising a base plate and an electron emitting element disposed on the base plate, the electron emitting element includes a plurality of electron emitting portions electrically connected in parallel, the electrical connection being made through a thermally cut-off member. After forming the plurality of electron emitting portions, their electron emission characteristics are checked and, for that electron emitting portion on which the electron emission characteristic has been found not normal, the electrical connection is cut off. Alternatively, the electron emitting element includes an electron emitting portion connected to a voltage supply through a thermally cut-off member, and an electron emitting portion forming film which includes a thermally connecting member. In this case, after cutting off the electrical connection in that electron emitting portion on which the electron emission characteristic has been found not normal, the electron emitting portion forming film is connected to the voltage supply for forming another electron emitting portion in the film. With such an electron source and an image forming device using the electron source, a production yield and image quality are improved.

    Abstract: An electron-emitting device is provided which comprises a laminate comprising an insulating layer (5) held between a pair of electrodes (1,2) opposing each other, wherein an electron-emitting region (3) insulated from said electrodes is formed at a side end surface of the insulating layer (5) formed at the part at which the electrodes oppose each other, and electrons are emitted from said electron-emitting region (3) by applying a voltage between said electrodes. A method for preparing the electron-emitting device is also provided.
