ELECTRON EMISSION DEVICE AND ELECTRON EMISSION DISPLAY USING THE SAME

摘要

An electron emission device and an electron emission display using the same are provided to improve electron emission uniformity in each of pixels by enhancing shape uniformity of an opening of a focusing electrode. A plurality of driving electrodes are formed on a substrate. A plurality of electron emission units(20) are electrically connected to at least one driving electrode. A focusing electrode(22) is positioned on an upper part of the driving electrodes in an insulating state. The focusing electrode includes at least one opening which is formed at each of pixels set on the substrate. The focusing electrode satisfies the following condition 1-[Wmax-Wmin/2Wave]>=0.95 where Wmax, Wmin, and Wave are a maximum width, a minimum width, and an average width, respectively. The driving electrodes include a plurality of cathode electrodes(14) and a plurality of gate electrodes(18) which are formed in a crossing direction on both sides of the insulating layer. At least one electron emission unit is formed on the cathode electrode with which the gate electrodes intersects.
