Abstract: A display device includes: a display panel to display a frame image by arranging line images; and a light source. One frame period includes sub-frame periods each including a writing period and a display period. The line images are written in units of a predetermined number of lines during the writing period. The line images that are written at a time in units of the predetermined number of lines are the same image. In two continuous sub-frame periods in the one frame period, when a line image to be written during the writing period in a preceding sub-frame period differs from a line image to be written during the writing period in a subsequent sub-frame period, a start position of the writing period in the preceding sub-frame period and a start position of the writing period in the subsequent sub-frame period are shifted by one line from each other.
