ABSTRACT:
The present invention provides an electron-emitting device which does not need a fresh electrode to be added thereto, has excellent convergence and shows little change of a discharged electric current for short and long periods of time, and an image display apparatus using the device. The electron-emitting device includes at least a pair of device electrodes formed on an insulating substrate, and a plurality of electroconductive films which are formed so as to connect the device electrodes to each other and have gaps therein, wherein the surface of a region which is at least adjacent to the gap between the electroconductive films and is not covered with the electroconductive film is higher than the surface of the electroconductive film.
