Display device

A display device comprising:

• an illuminating unit that includes a light source unit capable of emitting light;
• an illumination control unit that controls the illuminating unit;
• a display element that is capable of forming a display image using illuminating light from the illuminating unit;
• a display control unit that controls the display element;
• a control unit that controls the illumination control unit and the display control unit on the basis of a video signal;
• and
• a detection unit that detects a current output intensity of the light source unit,
• wherein
• the control unit stores therein a control value corresponding to a target output intensity of the light source unit,
• the control unit determines, on the basis of a difference between the target output intensity and the current output intensity detected by the detection unit, a correction value for correcting the control value, and
• the illumination control unit drives the light source unit on the basis of a control correction value in which the control value is corrected by the correction value.
