Abstract
A light-emitting cell, includes a light-emitting material which can emit light in response to a collision of an electron beam; an electron-emitting unit having a carbon nanotube as an electron source for releasing the electron beam and emitting the electron beam to ram against the light-emitting material; and a gate disposed above the carbon nanotube for controlling the electron beam emitting from the carbon nanotube whether to pass through the gate to ram against the light-emitting material at a specific address wherein the gate comprises a network conductor including a first metal layer for determining an x-coordinate of the address, a second metal layer for determining a y-coordinate of the address, and an extracting electrode placed between the carbon nanotube and the first metal layer for extracting the electron beam from the carbon nanotube.
