ABSTRACT:
A field emission display includes a first substrate, cathode electrodes formed on the first substrate, conductive layers formed on the cathode electrodes having first apertures to expose portions of the cathode electrodes, an insulating layer formed on the conductive layers and having second apertures communicating with the first apertures, gate electrodes formed on the insulating layer and having third apertures communicating with the second apertures, emitters formed on the cathode electrodes and within the first apertures, a second substrate provided opposing the first substrate with a predetermined gap therebetween; and an anode layer formed on the second substrate, and phosphor layers formed on the anode electrode. In a first direction, second and third measurements of the second and third apertures are larger than a first measurement of the first apertures, and each of the emitters is realized in an integral unit.
