An electron emission device to regularly emit electrons and a method of manufacturing the same. Also, an electron emission type backlight unit including the electron emission device in which a high voltage can be applied to an anode and required brightness can be obtained. In addition, the electron emission device can be manufactured using a simplified manufacturing process. The electron emission device includes a first electrode, a second electrode formed opposite the first electrode, and an electron emission layer which is electrically connected to one or each of the first and second electrodes and comprising carbide-derived carbon. The electron emission device may be a display device to form static or dynamic images.
