A field emission display includes a field emission cathode and an anode electrode plate arranged above the field emission cathode. The filed emission cathode includes a substrate, and a plurality of electron-emitting areas spaced apart from each other and arranged on the substrate. Each of the electron-emitting areas includes a cathode, a gate electrode, and a number of first and second conductive lines. The cathode includes a first conductive substrate and a first carbon nanotube assembly having a plurality of carbon nanotubes each having a cathode emitting end having a needle-shaped tip. The gate electrode is faced to the cathode emitting end. The taper-shaped tips of the cathode emitting ends and the gate have a small size and higher aspect ratio, allowing them to bear a larger emission current at a lower voltage.
A field emission cathode, comprising:
A field emission display, comprising:
The field emission display as claimed in claim 15, wherein the conductive film comprises of a material selected from a group consisting of copper, tungsten, aurum, molybdenum, platinum, and combinations thereof.
