Abstract
A carbon nanotube (CNT) field emission display has a cathode substrate having a cathode layer patterned on a glass substrate. The surface of the cathode layer is defined as a plurality of electron-emitting areas apart from each other, and a plurality of CNT structures is grown on the plurality of electron-emitting areas respectively.
Claims5
