ABSTRACT:
A field emission device (100) generally includes a front substrate (101) and a rear substrate (111) opposite thereto. The front substrate is formed with an anode (102). The rear substrate is formed with cathodes (112) facing the anode. A plurality of insulating portions (121) are formed on the rear substrate, each of which is arranged between every two neighboring cathodes. A plurality of gate electrodes are formed on top surfaces of the insulating portions121. Each of the gate electrodes has a getter layer (123) thereon.
