Flexible display panel and manufacturing method thereof, and display device

The invention discloses a flexible display panel and a manufacturing method thereof, and a display device. A groove is formed in a non-display region of a flexible substrate; the bottom of a first barrier dam is embedded into the first groove; and a packaging membrane layer covering a plurality of organic electroluminescent structures and a second barrier dam is arranged in a region limited by the first barrier dam. Therefore, interfaces in different directions are increased by using the first barrier dam so as to block an extension direction of a crack, so that extension of the crack caused at the edge of the flexible display panel to the display region can be prevented. Moreover, the bottom of the first barrier dam is embedded into the first groove of the flexible substrate and the first barrier dam in the first groove and the flexible substrate form interfaces in different directions, so that the extending direction of the crack can be blocked based on the interfaces; and thus extending of the crack to the display region can be prevented, so that an objective of reducing the opportunity of entrance of water and oxygen into the display region can be achieved and thus the influence on the organic electroluminescent structure by water and oxygen can be reduced. Therefore, the service life of the flexible display panel can be prolonged.
