ABSTRACT:
Backlight with which the uniformity of brightness within a display area of a concavely curved liquid crystal display device is improved while fulfilling the demand for slimmer liquid-crystal display devices, as well as curved liquid-crystal display device including such a backlight. The shape of a frame, an optical sheet, and a scattering plate constituting the backlight unit is the same concavely curved shape as that of the concavely curved panel; and the liquid-crystal panel, the optical sheet, and cold-cathode luminescent lamps are arranged such that the concavely curved panel, the surface of a frame constituting the backlight unit that faces the concavely curved panel, an optical sheet surface, and a surface including the tube center axes of a plurality of cold-cathode luminescent lamps are parallel to each other.
