Liquid crystal display device

A liquid crystal display device, comprising:

• a liquid crystal panel configured to display an image, the liquid crystal panel including a plurality of signal lines;
• a liquid crystal panel driving unit configured to provide a driving voltage to the plurality of signal lines;
• an image data judging unit configured to judge whether input image data is still image data or moving picture data;
• an image data correcting unit configured to correct moving picture data and output corrected moving picture to the liquid crystal panel driving unit;
• a plurality of light sources configured to provide light to the liquid crystal panel;
• and
• a light source driving unit configured to detect a display region having a motion value larger than a reference value from among an image of which frame data is displayed, based on a comparison of current frame data of the moving picture data with previous frame data of the moving picture data,
• wherein the light source driving unit is further configured to respectively control a part of the plurality of light sources corresponding to the detected display region and a remaining part of the plurality of light sources, based on the detected display region.
