Abstract:
In an embodiment of the present invention, in a liquid crystal display device which controls a light luminance of each of lighting regions, each of lighting regions of a backlight has a smaller width in a horizontal direction than in a vertical direction. This makes it possible to cause a reduction in contrast due to spatial distribution of light luminances, which spatial distribution is generated due to cross talk between lighting regions, to be less perceivable to an observer positioned in an oblique viewing direction.
