<p>An electron emission device and an electron emission display device using the same are provided to effectively focus electron beams from an electron emitter by adjusting a position relation between an opening and the electron emitter. An electron emission device includes a substrate(1), a cathode electrode(10), an electron emitter(20), a gate electrode(14), and a focusing electrode(18). The cathode electrode is formed on the substrate. The electron emitter is electrically connected to the cathode electrode. The gate electrode is arranged on the cathode electrode with a first insulation layer between them. A second opening, which intersects the cathode electrode and exposes the electron emitter, is formed on the gate electrode. The focusing electrode is formed over the gate electrode and a second insulation layer is formed therebetween. A fourth opening, which exposes the electron emitter, is formed on the focusing electrode. A center axis of the electron emitter is offset from a center axis of the fourth opening.</p> |
