Claim One:
1. A liquid crystal display comprising a light source, two or more data electrodes formed at specified intervals in a first direction, two or more scanning electrodes formed at specified intervals in a second direction orthogonal to said first direction, and a liquid crystal panel having two or more liquid crystal cells each being formed at an intersecting region of any one of said data electrodes and any one of said scanning electrodes wherein pixel data is fed to each of said liquid crystal cells when a scanning signal is sequentially applied to each of said scanning electrodes and corresponding pixel data is fed to each of said data electrodes and wherein modulation on light supplied from said light source is performed in a manner to correspond to an image to be displayed, said liquid crystal display comprising: said light source comprising two or more light source blocks being divided in said second direction of said liquid crystal panel; an image judging unit to divide one frame of a video input signal into two or more frame blocks each corresponding to a length of each of said light source blocks in said second direction and to judge whether an image corresponding to each of said frame blocks is a moving image or a static image; and a light source block driving unit to allow one of said light source blocks corresponding to an image for said frame block having been judged to be a moving image to flash according to a response characteristic of each of said liquid crystal cells to feeding of said pixel data and to allow one of said light source blocks corresponding to an image for said frame block having been judged to be said static image to be turned ON all the time.
