In a method for forming negative holes of a field emission display, a plurality of line patterns are first printed on a substrate, and then dried. The printing and drying of the line patterns are repeated until the line patterns are elevated to a predetermined height, then dot patterns are printed between the line patterns on the substrate and dried. The printing and drying of the dot patterns are repeated until the dot patterns are elevated to a predetermined height to define the negative holes enclosed by the line and dot patterns, and the line and dot patterns are simultaneously baked.

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.
