Abstract: Provided is a method for manufacturing an electric field emission device. The method for manufacturing the electric field emission device includes winding a carbon nanotube yarn around outer circumferential surfaces of a metal plate in a first direction, pressing both side surfaces of the metal plate through a pair of metal structures, wherein a top surface of the metal plate is exposed from the metal structures, and an area of the top surface of the metal plate is less than that of each of both the side surfaces of the metal plate, and cutting the carbon nanotube yarn at an edge portion of the top surface of the metal plate in the first direction to form a plurality of emitters.

Abstract: Provided is a high voltage driving device including a housing and a cathode, an anode, and an insulation structure, which are disposed in the housing. Here, the cathode and the anode are spaced apart from each other with the insulation structure therebetween. Also, the insulation structure includes a first solid insulator disposed adjacent to the cathode and a second solid insulator disposed adjacent to the anode. Also, the first solid insulator has first volumetric resistivity less than second volumetric resistivity of the second solid insulator, and the first solid insulator contacts the cathode.
