Abstract:
1. A method for making a field emission display, the method comprising the steps of: (1) providing a detachable substrate having a planar surface; (2) forming gate electrodes in a predetermined pattern on the planar surface of the detachable substrate; (3) forming an intermediate layer on the gate electrodes; (4) forming a catalyst layer on the intermediate layer; (5) forming a spacer on the catalyst layer, in a configuration corresponding to a predetermined pattern; (6) forming carbon nanotube arrays extending from the catalyst layer; (7) forming cathode electrodes on first ends of the carbon nanotube arrays; and (8) removing the detachable substrate, and removing portions of the intermediate layer corresponding to positions of the carbon nanotube arrays so as to expose opposite second ends of the carbon nanotube arrays to the gate electrodes.
