Abstract:
A liquid crystal display has pixel electrodes, a common electrode, a liquid crystal layer provided between the pixel electrodes and the common electrode, and a back light that supplies light transmitting through the liquid crystal layer, further has a control circuit that applies a drive voltage corresponding to image data between the pixel electrodes and the common electrode such that the polarity of the drive voltage is inverted for each predetermined period. Within a frame period, the control circuit applies a drive voltage of a first polarity in a first period, applies a drive voltage of a second polarity opposite to the first polarity, which is the same voltage as the drive voltage of the first polarity, in a second period after the first period, and controls such that the back light is turned off in the first period and turned on in the second period.
