Field emission array with carbon nanotubes

A field emission array comprising:

• a rear substrate assembly including:
• a rear substrate;
• a plurality of cathodes formed as stripes over the rear substrate;
• and
• a plurality of carbon nanotubes formed on the plurality of cathodes;
• and
• a front substrate assembly including:
• a front substrate;
• a plurality of anodes formed as stripes over the front substrate;
• a plurality of phosphors deposited on the plurality of anodes;
• a first and a second nonconductive plate, each having a plurality of openings separated by a distance corresponding to the distance between each of the plurality of anodes;
• a plurality of gates formed as stripes perpendicular to the stripes of the plurality of anodes on the first nonconductive plate with a plurality of emitter openings corresponding to the plurality of openings in the first nonconductive plate, wherein the distance between the plurality of gates and the plurality of carbon nanotubes is reduced;
• and
• a plurality of spacers for supporting and separating the second nonconductive plate from the front substrate,
• wherein the rear substrate assembly and the front substrate assembly are combined so that the plurality of carbon nanotubes on the plurality of cathodes project through the plurality of emitter openings.
