Abstract
An electron emission device includes a substrate; cathode electrodes formed on the substrate; electron emission regions electrically connected to the cathode electrodes; and gate electrodes positioned with the cathode electrodes with an insulating layer interposed between the cathode electrodes and the gate electrodes, the gate electrodes crossing the first electrodes to form a plurality of crossed regions. Here, at least two rows of the electron emission regions are placed at respective crossed regions along a longitudinal direction of the cathode electrodes, and the electron emission regions at the respective rows are deviated from each other in a longitudinal direction of the gate electrodes. In addition, the insulating layer and the gate electrodes have opening portions corresponding to the respective electron emission regions to expose the electron emission regions.
