A driving circuit of a liquid crystal display device and a method for driving the same, which are capable of reducing manufacturing cost of the liquid crystal display device and reducing a luminance deviation so as to improve image quality, are disclosed. The driving circuit of the liquid crystal display device includes an LED backlight which includes a plurality of LED modules arranged in a plurality of division areas and generates light, an internal photosensor which is mounted in any one of the plurality of division areas, for detecting a luminance value, a controller which generates and outputs a plurality of control signals for changing respective luminance values of the plurality of division areas according to the luminance value detected by the internal photosensor, and a plurality of LED drivers which drive the plurality of LED modules according to the plurality of control signals.
