<p>PROBLEM TO BE SOLVED: To provide an electron emission element, electron source, and image display with means for controlling the trajectory of electrons to prevent the reduction of efficiency and to obtain a highly precise electron beam with high efficiency, and provide on image display using it. SOLUTION: The electrode 4 of high potential is partly provided with a slit reaching the electrode 2 of low potential with an insulation layer 3 interposed between them. The electron emission part 6 is provided in the side wall of the slit.</p> |
