Abstract: In a backlight unit, a plurality of light sources whose luminescent chromaticities are different mutually, i.e., a white color fluorescent tube W, a red color fluorescent tube R, a green color fluorescent tube G, and a blue color fluorescent tube B, are arranged on both end in a longitudinal direction of a light guide plate respectively. The white color fluorescent tube W is arranged at a position closest to the end surface in a longitudinal direction of the light guide plate. Luminances of these fluorescent tubes W, R, G, B can be adjusted independently by control voltages supplied from external devices. Lights emitted from a plurality of light sources enter into the light guide plate, and then the lights are emitted from the light guide plate in a predetermined direction. Since the backlight unit itself has a color adjusting function, the reduction of the luminance and the change of the color balance due to degradation of the fluorescent tubes can be corrected.

The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.
