Abstract: A flexible display panel, a method for fabricating the same, and a display device are provided. A protruding structure located is formed in a via-hole area on a flexible base substrate so that both the protruding structure, and the portions of an organic light-emitting functional film and a top electrode layer covering the protruding structure can be removed. Thereafter an encapsulation thin film covering the patterns of the organic light-emitting functional film and the top electrode layer is formed. After the encapsulation thin film is formed, the step of removing the pattern of the encapsulation thin film in the via-hole area can be further performed to expose the flexible base substrate in the via-hole area, and after the flexible base substrate in the via-hole area is removed, a via-hole can be formed in the flexible base substrate.
