<p><P>PROBLEM TO BE SOLVED: To provide an electron emission element for suppressing beam diffusion to reduce another color-emission and suppressing diode type electron emission caused by an anode field, and to provide its manufacturing method. <P>SOLUTION: The element includes a substrate 2 having a concave part; an electron emission part 12 positioned by filling the concave part; and a cathode electrode 6 provided on the substrate 2 so as to be electrically connected to the emission part 12; and a gate electrode 10 formed on an upper part of the cathode electrode 6 through an insulation layer separating them. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
