A liquid crystal display (LCD) including a light emitting diode (LED) driving circuit and an LED module is provided. The LED module includes a plurality of LEDs. The LED driving circuit includes a transformer, a rectification circuit and a filter circuit. The transformer is used for outputting an AC voltage. The alternate current voltage is respectively rectified and filtered by the rectification circuit and the filter circuit, and then a direct current (DC) voltage level necessary for driving the LEDs is outputted accordingly.
