<p>Provided are a liquid crystal display device and a television receiver which enable an improvement in visibility in a low-tone range in a configuration in which the brightness of a backlight is changed on the basis of brightness information relating to an image, the liquid crystal display device is provided with an APL curve setting unit and a histogram brightness modulation unit which adjust the brightness of the backlight and a tone signal on the basis of the average brightness of the image and the brightness histogram of the image, and a black stretch unit which gamma-corrects the tone signal adjusted by the histogram brightness modulation unit on the basis of a previously set gamma value, wherein a gamma characteristic used for the gamma correction in the black stretch unit is set by, on the basis of correspondence information indicating the correspondence relationship between a combination of the brightness of backlight adjusted by the histogram brightness modulation unit and the environmental illuminance of the installation site of a liquid crystal panel, and a plurality of gamma values (?2.0-2.4), selecting a gamma value corresponding to the combination.</p> |
