PURPOSE: A field electron emitter and a method for manufacturing the same are provided to achieve improved uniformity of electron emission and lower driving voltages, while reducing a leakage current between a cathode and a gate. CONSTITUTION: A field electron emitter comprises a front substrate and a rear substrate(11) opposed each other with a gap formed therebetween; cathodes(12) formed into a stripe on the rear substrate; a plurality of micro tips(12') arranged on the cathodes and electrically connected to the cathodes; first, second, and third insulating layers(13a,13b,13c) formed on the cathodes and the exposed portion of the rear substrate in such a manner that the insulating layers have through holes for accommodating the micro tips; gates(14) formed on the insulating layers in the direction crossing the cathodes in such a manner that the gates have apertures(14') corresponding to the through holes of the insulating layers; anodes(17) formed into a stripe on the front substrate; and phosphor layers(16) formed on the anodes. The second insulating layer made from Al2O3 is interposed between the first and third insulating layers which are made from SiO2.
