Field emission display

A field emission display comprising:

• a transparent plate;
• an insulating substrate spaced relative to the transparent plate;
• and
• at least one grid located on the insulating substrate, wherein each grid comprises:
• a first, second, third and fourth electrode down-lead located on a periphery of the at least one grid, the first and the second electrode down-leads being parallel to each other, the third and the fourth electrode down-leads being parallel to each other, wherein the first, second, third and fourth electrode down-leads are insulated from each other;
• and
• a pixel unit comprising a first electrode, a second electrode spaced from the first electrode, a phosphor layer, and a plurality of electron emitter wires;
• wherein the first electrode electrically connects to the first electrode down-lead, the second electrode electrically connects to the third electrode down-lead, the phosphor layer is directly located on the first electrode, one end of each of the plurality of electron emitter wires electrically connects to the second electrode, and an opposite end of each of the plurality of electron emitter wires is spaced from the first electrode;
• and each of the plurality of electron emitter wires comprises a plurality of carbon nanotubes oriented around an axial direction of the at least one electron emitter wire.
