Display device with timing controller

A display device, comprising:

• a display panel which includes (i) a plurality of gate signal lines, (ii) a plurality of source signal lines provided so as to intersect the plurality of gate signal lines, and (iii) a plurality of pixels provided so as to correspond to respective intersections of the plurality of gate signal lines and the plurality of source signal lines;
• a signal line driving circuit that supplies a source signal to each of the plurality of pixels via a corresponding one of the plurality of source signal lines;
• and
• a timing controller;
• wherein
• the timing controller changes a refresh rate of the display panel;
• the timing controller changes at least one of a temporal cycle and a spatial cycle of a polarity reversal of the source signal in accordance with a change in the refresh rate;
• the timing controller shortens the spatial cycle in a case where the refresh rate is decreased;
• the timing controller lengthens the spatial cycle in a case where the refresh rate is increased;
• and
• the timing controller decreases the refresh rate of the display panel by securing a suspension time period, which directly corresponds to one or more frames of video, during which driving of the display panel is suspended.
