Abstract
A method of producing an electron-emitting device including the steps of forming a pair of electrodes and an electrically-conductive thin film on a substrate in such a manner that the pair of electrodes are in contact with the electrically-conductive thin film and forming an electron emission region using the electrically-conductive thin film, wherein a solution containing a metal element is supplied in a droplet form onto the substrate thereby forming the electrically-conductive thin film.
