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.

Abstract: A display device includes: a light emission control part which allows a light source to emit the light having one of the plural different main wavelengths in each of plural sub frames; a display panel which controls the transmission of light in each pixel; and a display control part which controls the display panel corresponding to a gray level value with respect to the each pixel, wherein the light emitting control part performs the light emission of light having a first main wavelength in a first sub frame in accordance with a light emission amount weighted based on a time for calculation including a first interval which is a interval between the first sub frame where the first main wavelength is emitted and a second sub frame where the first main wavelength is emitted after the first sub frame.
