A liquid crystal display and a driving method thereof. A gate driver drives a first pixel of the display via a first scanning line within a frame period including first and second data writing intervals. A first data voltage and a second data voltage are transmitted to the first pixel in the first and second data writing intervals, respectively. After the first data writing interval, a first color light source illuminates the first pixel. After the second data writing interval, a second color light source illuminates the first pixel. In a reset interval between the first and second data writing intervals, a voltage of a common line coupled to a storage capacitor of the first pixel is changed from a first common voltage to a second common voltage so that a voltage of a first liquid crystal capacitor of the first pixel is changed.
