Title: DISPLAY DEVICE
Abstract:
Provided is a display device capable of accurately controlling luminance of an illuminating unit. A display device (100) is provided with: an illuminating unit (10) having a light source unit (11) capable of emitting light; an illumination control unit (91) that controls the illuminating unit; a display element (30) capable of forming an image using illuminating light C transmitted from the illuminating unit (10); a display control unit (92) that controls the display element (30); a control unit (90) that controls the illumination control unit (91) and the display control unit (92) on the basis of video signals (300); and a detection unit (40) that detects the output intensity of the light source unit (11) at that time. The control unit (90) stores a control value d2 corresponding to a target output intensity (p2) of the light source unit (11), and on the basis of a difference between the target output intensity p2 and the output intensity p1 at that time, the control unit (90) determines a correction value ∆ for correcting the control value d2, and on the basis of a control correction value d2' obtained by correcting the control value d2 using the correction value ∆, the illumination control unit (91) drives the light source unit (11).
