Abstract
The present invention relates to a liquid crystal display device in which the light sources of a backlight unit are independently driven as a plurality of separate regions, and to a drive method for the same. In situations where there is a substantial variation in the brightness (luminance) of regions being displayed on the liquid crystal display device, the present invention can improve the visibility of boundaries due to differences in luminance in images displayed within the regions of the backlight unit emitting light at different levels of luminance as a result.
