    摘要： A control circuit changes the ratio of an illumination period to a non-illumination period in a frame period of a backlight according to a gradation level in the one frame period of an image displayed on a liquid crystal panel in such a manner that the higher the gradation level, the backlight illumination control circuit increases the ratio of the illumination period to the non-illumination period in the frame period of the backlight, and the lower the gradation level, the backlight illumination control circuit decreases the ratio of the illumination period to the non-illumination period in the frame period of the backlight and thereby controls illumination intensity toward the liquid crystal panel. A time center of illumination intensity in each one frame period of the backlight is controlled in order that the time center exists in a constant temporal position from the beginning of each frame period.

    摘要： A backlight illumination control circuit changes the ratio of an illumination period BL to a non-illumination period in a frame period V of a backlight according to a gradation level in the one frame period V of an image displayed on a liquid crystal panel in such a manner that the higher the gradation level, the backlight illumination control circuit increases the ratio of the illumination period BL to the non-illumination period in the frame period V of the backlight, and the lower the gradation level, the backlight illumination control circuit decreases the ratio of the illumination period BL to the non-illumination period in the frame period V of the backlight and thereby controls illumination intensity toward the liquid crystal panel. A time center of illumination intensity in each one frame period V of the backlight is controlled in order that the time center exists in a constant temporal position T from the beginning of each frame period V. This realizes a liquid crystal display device being free from perceived flickers, giving a high contrast feeling, and being excellent in the performance of moving image display.

    摘要： A backlight device includes a light diffusing member above a plurality of light sources that are partitioned into a plurality of illumination regions by a partition wall. A light incidence plane at which lights from the plurality of light sources enter is higher than the light sources and equal to or lower than a top of a partition wall. Moreover, a second light diffusing member is laminated above the light diffusing member so that a space is provided between the second light diffusing member and the first light diffusing member. The second light diffusing member has a light incidence plane in a position at a height that is higher than the top of the partition member. This makes it possible to independently control each of the illumination regions.

    摘要： A backlight (illumination device) (2) of the present invention includes a plurality of light sources (5) and a plurality of light guides (7, 17, . . . ) that allow light entered into the light guides from the plurality of light sources (5) to be emitted from surfaces of the plurality of light guides (7, 17 . . . ). Each of the light guides (7, 17, . . . ) includes: a light emitting section (7b, 17b, . . . ) that has a light emitting surface (7a); and a light guide section (7c) that guides, to the light emitting section (7b, 17b, . . . ), light entered into the light guides from the plurality of light sources (5). Each of the light guides (7, 17, . . . ) is also arranged such that the light emitting section (17b) of the light guide (17) that is adjacent to the light guide (7) overlaps the light guide section (7c) of the light guide (7). An edge surface (7e) of the light emitting section (17b) of the light guide (17) that overlaps the light guide (7) has concaved and/or convexed shape. The concaved and/or convexed shape serves as a light intensity adjusting section that reduces light transmission quantity.
