The invention provides a liquid crystal module and a curved surface display device. According to the liquid crystal module and the curved surface display device, a curved surface liquid crystal panel can be kept stable, and deformation of the curved surface liquid crystal panel is reduced. The liquid crystal module comprises the liquid crystal panel and a backlight source, wherein the backlight source comprises a light guiding plate. The light-emitting surface, facing the liquid crystal panel, of the light guiding plate is an inwards-concave arc-shaped curved surface, the liquid crystal panel is in an inwards-concave arc shape, and the liquid crystal panel is arranged on the light-emitting surface of the light guiding plate through a connecting member, wherein the curvature of the arc of the liquid crystal panel is the same as that of the light-emitting surface of the light guiding plate.
