An electron emission device with improved electron emission efficiency and an electron emission type backlight unit with a new structure using the electron emission device in which an electric field between an anode electrode and a cathode electrode is effectively blocked, and electrons are emitted continuously and stably by a low gate voltage thereby improving light-emitting uniformity and light-emitting efficiency. Also provided is a flat display apparatus employing the electron emission type backlight unit having the electron emission device. The electron emission device includes a base substrate; a cathode electrode formed on the base substrate; a gate electrode that is formed on the base substrate and alternately separated from the cathode electrode when there are more than one; an electron emission layer disposed on a surface of the cathode electrode; and a supplementary electrode formed on the cathode electrode or the gate electrode and is higher than the corresponding electrode. |
