Abstract
A three-dimensional (3D) image display device includes a liquid crystal display panel alternately displaying a left eye image and a right eye image every unit frame period, a data driving circuit, a gate driving circuit, a timing controller that divides the unit frame period into first and second sub-frame periods, repeatedly supply the same frame data to the data driving circuit during the first and second sub-frame periods, and control operations of the data and gate driving circuits using a frame frequency higher than an input frame frequency, backlight light sources generating light to be provided to the liquid crystal display panel, and a light source driving circuit that sequentially turns on the backlight light sources when liquid crystals of the liquid crystal display panel are kept in a saturation state.
