1. A display device comprising:

  • a first change unit configured to change a transmittance of a liquid crystal panel in synchronization with a first timing;

    a second change unit configured to change brightness of a backlight of the liquid crystal panel in synchronization with a second timing;

    a microcomputer configured to calculate delay time for delaying the second timing relative to the first timing and couple the calculated delay time to a delay control unit, the calculated delay time being calculated based on a time until the transmittance of the liquid crystal panel changes by a predetermined amount at a given response speed and being less than a time for the transmittance of the liquid crystal panel to change by the predetermined amount;

    a backlight value calculation unit configured to generate a backlight data for reducing a lighting amount of a backlight corresponding to an area of low luminance (dark part) in an image and increasing the lighting amount of the backlight corresponding to an area of high luminance (bright part) in the image and output the generated backlight data to the second change unit at the second timing instructed from the delay control unit; and

    the delay control unit configured to;

    make the first change unit change the transmittance of the liquid crystal panel in synchronization with the first timing, andmake the second change unit change the brightness of the backlight in synchronization with the second timing delayed from the first timing by the calculated delay time.
