An electron emission device and a manufacturing method of the same are provided to suppress a screen effect of an electron emission unit by forming carbon based materials at a predetermined interval. A plurality of cathode electrodes(6) are formed on a substrate(2). A catalytic layer is formed on the cathode electrodes. A crack layer is formed on the catalytic layer in order to form fine cracks on the catalytic layer. An electron emission unit(12) is formed on the catalytic layer exposed through the fine cracks. A plurality of gate electrodes(10) are formed between the cathode electrodes and the insulating layer. The gate electrodes include apertures for opening the electron emission unit.
