A triode type flat lamp (4.5-in.) using screen printed carbon nanotube emitters was fabricated. The spacer of about 200um between the cathode and gate electrode with a metal mesh was placed by the simple screen printing technique, which does not correspond with method of the past. The buried CNTs were exposed on the surface by the electric field condition without other mechanical surface treatments. A high brightness of 10100 cd / m2 with relatively homogenous emission sites was obtained at the voltage of gate and anode of D.C. bias 280 V and 3KV, respectively. The turn-on voltage was 180 V and the anode current of 5 mA was extracted at the gate voltage of 275 V. Through accurate alignment of the gate holes and the CNT dots, the gate leakage current was significantly decreased including emitted electrons focusing effect.
