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.
