Abstract: The present disclosure provides a flexible display device, wherein there is a flexible support structure fixed on a surface of the flexible display module, which is used to disperse stress. During use of the flexible display device, the flexible support structure can be used to disperse the point force or linear force that the flexible display device is subject to when being bent into even planar force. Besides, the flexible support structure can reduce the stress exerted on the flexible display module, avoiding delamination among the film layers caused by local stress concentration on the flexible display module. In addition, given the same thickness of the flexible display module, the flexible display device can be bent to a smaller bending radius.

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.
