Abstract:
A field emission display includes a first substrate; a plurality of gate electrodes formed on the first substrate in a predetermined pattern; an insulation layer formed covering the gate electrodes over an entire surface of the first substrate; a plurality of cathode electrodes formed on the insulation layer in a predetermined pattern, a plurality of emitters formed on the cathode electrodes; a plurality of counter electrodes formed on the insulation layer at a predetermined distance from the emitters and in a state of electrical connection to the gate electrodes, the counter electrodes forming an electric field directed toward the emitters; a second substrate provided at a predetermined distance from the first substrate and sealed in a vacuum state with the first substrate; an anode electrode formed on a surface of the second substrate opposing the first substrate; and a plurality of phosphor layers formed over the anode electrode in a predetermined pattern.
