An electron emission display device is provided having a light source unit including a plurality of cathode electrodes and a plurality of gate electrodes crossing the plurality of cathode electrodes. The light source unit emits electrons corresponding to voltages of the gate electrodes and the cathode electrodes and allows the emitted electrons to collide with a phosphor on an anode electrode to emit light. A gate driver generates a gate signal and transmits the gate signal to at least one of the gate electrodes. A cathode driver generates a cathode driving signal corresponding to an image signal and transmits the cathode driving signal to the cathode electrode. The cathode driving signal is transmitted in a plurality of pulse waveforms within one vertical synchronization period.
