<p>An electron emission device and an electron emission display having the same are provided to increase focuss efficiency of an electron beam by optimizing displacement of openings of a focuss electrode and openings of gate electrodes. An electron emission device includes substrates(2,4), cathode electrodes(6) formed on any one of the substrates, an electron emission part(12) electrically connected to the cathode electrode, gate electrodes(10) formed on a first insulating layer(8) formed on the cathode electrodes, and focuss electrodes(14) formed on a second insulating layer(16). Plural openings(101) are formed on the gate electrodes at every across region of the cathode electrode and the gate electrode, and openings(141) corresponding to the openings of gate electrode are formed on the focuss electrodes.</p> |
