Abstract
In a liquid crystal display and a method of driving the same, the liquid crystal display includes: a liquid crystal display panel having a matrix of a plurality of pixels arrayed two dimensionally in a first direction and in a second direction crossing the first direction; and an illuminating device including a plurality of light sources facing the pixel matrix of the liquid crystal display panel. The plurality of light sources are arrayed in the first direction and grouped into a plurality of light source areas. The turn-on start timing of light sources in each light source area is set to a specific timing based on the input timing of the video signal to the selected pixel rows in the pixel matrix. Further, the turn-on and turn-off timings of the light source areas are set to specific conditions.
