1. A display device comprising:
a display panel comprising a plurality of pixels; and
a light source device configured to emit light that illuminates the display panel, wherein
the display panel is configured to control operation of the light source device,
the display panel does not lower luminance of the light for a second predetermined time or longer after the display panel has raised the luminance of the light by a predetermined amount of luminance change or more within a first predetermined time, and
when an image changes from a first image other than a raster image and a ramp image to a second image that is either of the raster image and the ramp image, the display panel lowers the luminance of the light within a time shorter than the second predetermined time even after the luminance of the light has been raised by the predetermined amount of luminance change or more within the first predetermined time.
