Disclosed are a curvature adjustable composite back panel and a curvature adjustable backlight module, which are used in a curvature adjustable liquid crystal display device, wherein the composite back panel comprises: a fixing plate (110); a back panel (120), comprising a middle part (121), with the middle part (121) being fixed on the fixing plate (110); and at least two telescopic control devices (170), arranged between the back panel (120) and the fixing plate (110) and respectively arranged on two sides of the middle part (121). The telescopic control devices (170) control the distance between the back panel (120) and the fixing plate (110) by extending or contracting so as to adjust the curvature of the back panel (120) and accordingly adjust the curvature of the liquid crystal display device. |
