Abstract:
A liquid crystal display device that performs phase inversion drive in which a phase of a polarity of a data voltage is inverted in predetermined timing while performing frame inversion drive in which a positive-polarity data voltage and a negative-polarity data voltage are alternately output to a data line in each one or plurality of frames. In a first frame immediately after the phase is inverted, the source driver outputs a second data voltage to the data line in initial first periods of a horizontal scanning period, the second data voltage being closer to the common voltage than a first data voltage corresponding to input image data, and outputs the first data voltage to the data line in a second period after the first period in the horizontal scanning period.
