ELECTRON EMISSION DEVICE AND ELECTRON EMISSION DISPLAY DEVICE HAVING THE SAME

摘要

An electron emission device and an electron emission display device having the same are provided to prevent dispersion of an electron beam when the electron beam passes through focus electrodes. Cathode electrodes(110) are formed on a substrate(10), and an electron emission part(140) is formed on the cathode electrode. Gate electrodes(130) are formed on the cathode electrodes, and have openings(120a,130a) corresponding to the electron emission part. Focus electrodes(160) are formed on the gate electrodes, and have openings at portions in which the cathode electrodes intersect the gate electrodes. A resistor layer(170) is formed at a region around the electron emission part.
