Patent ID: 8125439

Claim:
A liquid crystal display apparatus comprising: a liquid crystal panel having a plurality of pixels arranged in a matrix form; a back light having a plurality of light sources which can be controlled individually in light emission luminance to supply light to the liquid crystal panel; an image processing unit configured to calculate luminance setting values respectively of the light sources of the back light on the basis of a video signal and correct the video signal on the basis of the luminance setting value of each light source; a back light control unit configured to control the back light on the basis of luminance setting values; and a liquid crystal drive unit configured to drive the liquid crystal panel on the basis of the corrected video signal, wherein in strength distribution of light incident on the liquid crystal panel from each of the light sources, a relative strength compared with a direct component in spatial frequency domain is equal to or less than a first threshold in a spatial frequency region having a value of at least 1.
