Abstract
A liquid crystal display device includes a liquid crystal display panel having first and second scanning lines, first and second video lines, a first scanning line driving circuit, a second scanning line driving circuit, at least one first video line driving circuit, at least one second video line driving circuit, a backlight having a number of light sources, and a light controlling circuit for controlling the turning on and off of the backlight. The first scanning lines are divided into M groups where M is an integer of 2 or more (M≧2), the second scanning lines are divided into N groups where N is an integer of 2 or more (N≧2), the region of the backlight which corresponds to the first scanning lines is divided into M regions, and the region which corresponds to the second scanning lines is divided into N regions.
