Abstract: The present invention relates to a display device, and particularly to a backlight for a curved-surface liquid crystal display device and a curved-surface liquid crystal display device. The backlight comprises: a backplane which matches a curved-surface LCD display screen of the curved-surface liquid crystal display device; a supporting member which comprises a plurality of stepped surfaces parallel with a base plate of the backplane; and light sources which are arranged on each of the stepped surfaces, wherein the plurality of light sources form a curved surface projecting to one direction, and the projecting direction of the curved surface is the same as that of the curved-surface LCD display screen. Due to the stepped structure, the optical distribution of light sources along the curved surface is realized without bending mechanical structures and optical components of the backlight, and the fabrication difficulty of the backlight is reduced.
