An LCD includes a display panel, a plurality of fluorescent lamps, an electric field sensor, and an inverter. The electric field sensor senses electric fields of the plurality of fluorescent lamps to generate a voltage. The inverter is electrically connected the plurality of fluorescent lamps, and generates a driving voltage to drive the plurality of fluorescent lamps. The inverter adjusts an operating frequency of the driving voltage according to the voltage. Thus, the waving phenomenon of the LCD is improved effectively.
