The invention mainly discloses a reinforced supporting sheet and a foldable display comprising the same, and the reinforced supporting sheet is integrated in the foldable display to be attached to the bottom surface of a display panel and is used for supporting the display panel. According to the invention, the reinforced support sheet comprises a substrate and a corrugation structure, and the top surface of the substrate is used for being attached to and connected with the display panel, so that the corrugation structure covers a bending area of the display panel. According to the design, when the display panel is bent, the corrugation structure buffers stress applied to the bending area, so that residual stress accumulated in the bending area is reduced, and creases and cracks in the bending area are avoided. Due to the fact that the corrugated structure has high strength and rigidity, the display panel can be well supported.
