Abstract: A display device includes a control circuit. By setting an intermediate point between a start point and an end point of a lighting period as a start point of the lighting cycle, and setting an intermediate point between a start point and an end point of a lighting period of the next lighting period as an end point of the lighting cycle, the control circuit controls a backlight such that an absolute value of a difference value between a first ratio of a sum of a length of a first lighting period in the first lighting cycle and a length of the next second lighting period in the first lighting cycle to a length of the first lighting cycle and the target duty ratio is 0.1 or less.
