Abstract
A color field emission display includes a sealed container and a color element enclosed in the sealed container. The color element includes a cathode, an anode, a phosphor layer and a carbon nanotube string. The anode is located spaced from the cathode. The phosphor layer is formed on an end surface of the anode. The carbon nanotube string has a first end electrically connected to the cathode and an opposite second end functioning as an emission portion. The second end includes a plurality of tapered carbon nanotube bundles.
