Abstract: PROBLEM TO BE SOLVED: To make the electron beam over a fluorescent surface small, and enlarge the assem bling margin of an electron source substrate with a face plate by letting an electron emitting part be a crack extended along the side of an electrode located closer to the side of one element electrode rather than the intermediate position between both the element electrodes. SOLUTION: An electron emitting part 3 represents a crack high in resistance, which is formed in a place close to an element electrode 6 of a thin film 4 including the electron emitting part 3. The aforesaid crack is so disposed that the electron emitting part 3 is extended along the side of an electrode which is located closer to the electrode 6 side rather than the intermediate position of the element electrodes 5 and 6. In this case, since the film thickness distribution of the thin film 4 is thin in a place close to the electrode 6, when energizing forming is performed, the crack is formed in a place close to the electrode 6 the resistance of which is high. Besides, there exist fine conductive particles in the inside of the crack, and the fine conductive particles contain at least some elements of material forming the thin film 4.  When completed elements are driven, if the potential of the electrode 6 is made lower than that of the electrode 5, some constituents of discharged electrons which are dark over the fluorescent surface, and are in a distorted shape each, are deflected by the electric field of an electrode close to the electrode 6 so as to be forwarded to the electrode 5.
