Provided is a field sequential image display device with which the service life of DMD display elements can be lengthened. In the present invention, each frame is equipped with: a display period, wherein a display control portion normally drives multiple mirrors and a lighting control portion drives a first lighting portion and a second lighting portion, thereby displaying a display image in display elements; and a non-display period, wherein the display control portion drives the multiple mirrors for a non-display period and the lighting control portion turns off the first lighting portion and the second lighting portion, and thus the display image is not displayed in the display elements. On the basis of prescribed luminance control conditions, when the luminance of the display image is to be lower than a predetermined threshold luminance value, a control unit lowers the display period ratio, which is the ratio of the display period in each frame period.
