ABSTRACT:
A lateral field emission display in which a cathode and anode are laterally arrayed, and a fabricating method thereof, since the micro tip is formed to be sharp through the reactive ion etching method, efficiency of electron emission is better than a conventional wedge-type tip. Also, since focusing of an electron beam is accurately controlled, a relatively low-voltage driving is possible. Further, since the first gate is further provided above the cathode and the anode is formed to be higher than the second gate, a trace control of an electron-beam emitted from the micro tip is easy and focusing efficiency of the emitted electron beam to the anode is also improved.
