Abstract: A flexible liquid crystal display panel and a display device are disclosed. The flexible liquid crystal display panel comprises: a first flexible substrate and a second flexible substrate arranged oppositely; a first polarizer on a side of the first flexible substrate facing away from the second flexible substrate; a second polarizer on a side of the second flexible substrate facing away from the first flexible substrate; and a positive C plate compensation film and a first negative A plate compensation film arranged on the second flexible substrate; the positive C plate compensation film is arranged between the second flexible substrate and the first negative A plate compensation film. The light leakage defect of a visual angle greater than zero in a dark state can be overcome, which occurs since the absorption axis of the first polarizer and the absorption axis of the second polarizer are not perpendicular to each other.
