An electron emission device having improved electron emission efficiency and an electron emission type backlight unit including 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; an insulating layer disposed on a surface of the base substrate; a cathode electrode formed on the insulating layer; a gate electrode that is formed on the base substrate, separated from the cathode electrode, and higher than the cathode electrode; and an electron emission layer that is electrically connected to the cathode electrode and disposed to face the gate electrode. |
