Disclosed herein is a bipolar pulse generator capable of generating a bipolar pulse, in which pulse widths of a positive pulse and a negative pulse are symmetrical, in order to smoothly turn on a carbon nanotube (CNT) lamp. The bipolar pulse generator includes a driving power supply source which outputs a driving voltage for generating a bipolar pulse; an inverter which al¬ ternately generates positive and negative pulses, of which the pulse widths are symmetrical, using the driving voltage and outputs a rectangular wave bipolar pulse; and a resonance circuit which converts the rectangular wave bipolar pulse into a sinusoidal wave bipolar pulse and increases the level of the bipolar pulse.
