Abstract
A pixel tube for field emission display includes a sealed container, an anode, a phosphor, and a cathode. The sealed container has a light permeable portion. The anode is located on the light permeable portion. The phosphor layer is located on the anode. The cathode is spaced from the anode and includes a cathode emitter. The cathode emitter includes a carbon nanotube pipe. One end of the carbon nanotube pipe has a plurality of carbon nanotube peaks.
