Abstract
A display device includes: an illuminating unit having a light source unit emitting light; an illumination control unit controlling the illuminating unit; a display element forming an image using illuminating light from the illuminating unit; a display control unit controlling the display element; a control unit controlling the illumination control unit and the display control unit based on a video signal; and a detection unit detecting the output intensity of the light source unit at that time. The control unit stores a control value corresponding to a target output intensity of the light source unit, and based on a difference between the to target output intensity and the output intensity at that time, the control unit determines a correction value for correcting the control value, and based on a control correction value obtained by correcting the control value using the correction value, the illumination control unit drives the light source unit.
