中文摘要：

Based on simple screen printing technique,the parallel grid electrode group was developed. One grid electrode included the left and the right branch electrodes,which were formed with the solidified silver slurry on grid substrate. Under one anode pixel,the left and the right branch electrodes would control respectively the electron emission of two independent carbon nanotube (CNT) field emitters on the same cathode electrode. With the parallel grid electrode group, the capacitance effect between grid-cathode electrodes would be reduced due to the decreased grid electrode fabrication area. And the service life of field emission display (FED) could be prolonged owing to the existence of spare branch electrode. Using CNT as field emitter,the FED with parallel grid electrode group was fabricated,which possessed better grid control performance, high luminescence image brightness, and low fabrication cost. The turn-on electric-field was 2. 13 V /mm and the maximum field emission current had reached 1 506. 2 mA.
