An embodiment of the present invention relates to the technical field of display. Particularly, there is provided a flexible screen and a bend identifying method thereof, as well as a flexible display apparatus. The flexible screen comprises a first flexible substrate and a second flexible substrate which are oppositely disposed; the flexible screen further comprises a first electrode which is disposed on one side close to the second flexible substrate of the first flexible substrate and a second electrode which is disposed on one side close to the first flexible substrate of the second flexible substrate, as well as a detection system connected with the first electrode or the second electrode; wherein the first electrode and the second electrode are configured to be in positional correspondence; in a case where the flexible screen is bent, the first electrode and the second electrode are electrically connected. The present invention is used for fabrication of a display apparatus. The present invention may be used for determining whether the flexible screen is excessively bent or flexed.
