In a display device (i) which carries out a display based on a video signal whose resolution has been converted to higher resolution (high-resolution conversion driving) and (ii) which carries out CC driving, when the resolution of the video signal is converted by a factor of 2 (double-size display), assuming that a direction in which the gate lines extend is a row-wise direction, signal potentials having the same polarity and the same gray scale are supplied to pixel electrodes included in respective two pixels that correspond to two adjacent gate lines and that are adjacent to each other in the column-wise direction (scanning direction), and a direction of change in the signal potentials written to the pixel electrodes from the source lines varies every two adjacent rows according to the polarities of the signal potentials.
