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 (F) is equipped with: a display period (Fa), wherein a display control portion (92) normally drives multiple mirrors (E) and a lighting control portion (91) drives a first lighting portion (11r) and a second lighting portion (11g), thereby displaying a display image (D) in display elements; and a non-display period (Fb), wherein the display control portion (92) drives the multiple mirrors (E) for a non-display period and the lighting control portion (91) turns off the first lighting portion (11r) and the second lighting portion (11g), and thus the display image (D) is not displayed in the display elements. On the basis of prescribed luminance control conditions, when the luminance of the display image (D) is to be lower than a predetermined threshold luminance value (T), a control unit (90) lowers the display period ratio (A), which is the ratio of the display period (Fa) in each frame period. |
