Abstract: A method for manufacturing a flexible display panel and the flexible display device are disclosed. The method for manufacturing the flexible display panel includes: forming a substrate, a flexible display and an overcoat layer on a support substrate in sequence; flipping over so that one side provided with the support substrate is placed upward; stripping off the support substrate; coating a curable material on a surface obtained after the support substrate is stripped off; and performing a curing process so that the coated curable material is cured to form a protective film. The method for manufacturing the flexible display panel can form the protective film without adopting laminating/bonding devices, is simple and easy, and does not require the vacuum defoamation process subsequently.
