The embodiment of the invention relates to the field of display technology, and provides a curved surface display device whose curvature can be adjusted flexibly after assembly. The curved surface display device may comprise a liquid crystal display module, and may also comprise at least one adjustment frame, each adjustment frame comprises a first portion and a second portion, both of the first portion and the second portion comprise a fixed end and a movable end, the fixed end of the first portion and the fixed end of the second portion are respectively attached to the two edges of the liquid crystal display module that are perpendicular to the horizontal direction in case of being viewed normally; an adjustment distance is present between the movable end of the first portion and the movable end of the second portion, the adjustment frame is provided with an adjustment screw which movably connects the movable end of the first portion and the movable end of the second portion; the adjustment frame is used for changing the size of the adjustment distance by regulating the adjustment screw, so as to vary the curvature of the liquid crystal display module. Embodiments of the invention may be used for manufacturing the curved surface display device.
