A pixel tube for field emission display includes a sealed container, three anodes, three phosphor layers, and a cathode. The sealed container has a light permeable portion. The three anodes are located in the sealed container. Each of the three phosphor layers is located corresponding to one of the three anodes. The cathode is spaced from the three anodes and includes three cathode emitters. Each of the three cathode emitters is located corresponding to one of the three phosphor layers and includes a carbon nanotube pipe. One end of the carbon nanotube pipe has a plurality of carbon nanotube peaks. |
