Abstract: A flexible support plate and a flexible display device. The flexible support plate comprises an opening area (2) and at least one solid area (1) arranged on at least one side of the opening area (2), wherein the opening area (2) is provided with a plurality of through holes (3); the opening area (2) comprises a central area (21) and a transition area (22); the transition area (22) is arranged between the central area (21) and the solid area (1); and the width of the transition area (22) decreases as the distance from the central area (21) increases. When the flexible support plate is bent, the transition area (22) gradually deforms, and the stress is also gradual, without a sudden change, that is, the stress changes relatively uniformly, thereby avoiding hard-angle bending caused by a sudden stress change during bending, and accordingly avoiding problems of film-layer separation and cracks. The flexible support plate can be applied to flexible display devices with smaller bending radii.
