The embodiment of the invention provides a light guide plate, a backlight source, a display device and point collision equipment and method for manufacturing the light guide plate. A bottom surface ofthe light guide plate comprises a first area positioned in a curved surface structure and a second area beyond the first area; the first area and a transitional area, adjacent to the edge of the first area, in the second area are provided with first net points, and the outer surfaces of the first net points are of preset surface roughness so that part of incident light is diffuse-reflected to thelight emitting surface corresponding to the first area and emitted; and other areas in the second area are provided with second net points. The rough first net points are additionally arranged in thecurved-surface structure and the edge of the bottom surface of the light guide plate, corresponding incident light in the non-curved-surface structure is transmitted to the curved-surface structure,light is emitted in the full-reflection way by the second net points in other areas, the brightness of the curved-surface structure is improved on the premise that the brightness of the backlight source is ensured, and the problem that an ultra-dark corner is adverse is solved.
