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. In the above technical solution, 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. Meanwhile, the light sources are horizontally arranged on the stepped surfaces in the same direction, so that the light sources have the same light exiting direction, enabling the backlight to provide more uniform light, which improves the display effect of the display device.

Abstract translation: 显示装置技术领域本发明涉及显示装置，特别涉及用于曲面液晶显示装置和曲面液晶显示装置的背光源。 背光源包括：与曲面液晶显示装置的曲面LCD显示屏相匹配的背板; 支撑构件，其包括与所述背板的基板平行的多个台阶表面; 以及布置在每个台阶表面上的光源，其中多个光源形成向一个方向突出的弯曲表面，并且曲面的突出方向与曲面LCD显示屏的突出方向相同。 在上述技术方案中，由于台阶结构，在弯曲背光的机械结构和光学部件的情况下实现光源沿着曲面的光分布，并且降低了背光的制造难度。 同时，光源在相同方向上的台阶表面上水平布置，使得光源具有相同的光出射方向，使背光提供更均匀的光，从而改善了显示装置的显示效果。
