Consequently, controller 30 does not output the image data and various control signals corresponding to the second pixel row to source driver 24 when supplying the data voltage to the second pixel row having the correlation with the first pixel row. That is, source driver 24 maintains the data voltage supplied to the first pixel row during a timing when the data voltage can be supplied to the second pixel row. Thus, because source driver 24 is driven once when the data voltage is written in the first pixel row and the second pixel row having the correlation with the first pixel row, the number of drive times of source driver 24 in one frame is reduced, leading to the reduction of the power consumed by source driver 24. That is, the power consumed by liquid crystal panel 20 including image display region 21, source driver 24, and gate driver 25 is reduced. Because the second pixel row has the correlation with the first pixel row in the image, the image quality degradation is hardly generated even if the data voltage of the first pixel row is written in the second pixel row.
Thus, liquid crystal display device 10 can reduce the power consumed in liquid crystal panel 20 while preventing the generation of the image quality degradation. Since the power consumed by source driver 24 has a large ratio of the power consumed by liquid crystal panel 20, the power consumed by liquid crystal panel 20 can effectively be reduced by decreasing the number of drive times of source driver 24.
