Flexible display panel, its manufacturing method, and flexible display device

Abstract

A flexible display panel, a manufacturing method thereof, and a flexible display device are disclosed. The flexible display panel includes a flexible substrate, the flexible substrate including a display area, a peripheral area, a pad area, and a bending area including a first edge. The flexible display panel further includes a barrier and an organic insulating layer. The peripheral area includes a peripheral transition area located between the bending area and the display area. A first groove is formed in the organic insulating layer in the peripheral transition area, the first groove being located on a side of the barrier away from the display area and extending in a direction substantially parallel to the bending axis, and the first groove is located on a side of the first edge closer to the display area. The first groove is formed in the organic insulating layer in the peripheral transition area to facilitate the release of bending stress and prevent fracture of the bending area.
