Patent ID: 8063922

Claim:
A liquid crystal display device including a liquid crystal panel, a backlight for illuminating the liquid crystal panel, and a control unit configured to control intensity of illumination light of the backlight, wherein: according to a gradation level in unit time of an image displayed on the liquid crystal panel, the control unit is configured to control the intensity of the illumination light toward the liquid crystal panel by changing a ratio of an illumination period to a non-illumination period of the backlight in the unit time in such a manner that the higher the gradation level, the control unit increases the ratio of the illumination period to the non-illumination period of the backlight in the unit time, and the lower the gradation level, the control unit decreases the ratio of the illumination period to the non-illumination period of the backlight in the unit time; and the control unit is configured to controls the intensity of the illumination light in such a manner that in each of a plurality of consecutive units time a time center of the intensity of illumination light of the backlight is constantly at a same temporal position from the beginning of the unit time.
