Abstract: Provided are a display device that can suppress occurrence of a color breakup as well as occurrence of a false contour, and a control method therefor. In the display device, a plurality of sub-frame periods forming one frame period are divided into a first group to which sub-frame periods with the same length of light transmission periods belong; and a second group to which sub-frame periods with lengths of light transmission periods shorter than those of the sub-frame periods in the first group and different from each other belong. Further, among the sub-frame periods that belong to the first group, sub-frame periods having the light transmission period increase in number from a middle of the one frame period toward a start point and an endpoint of the one frame period in accordance with an increase of the gray level.
