Abstract: Provided are a flexible display panel and a flexible display device, in which a non-display area surrounds a display area. A concave area protrudes along a direction away from interior of display area. A convex area has a folding axis parallel to a first edge. The non-display area includes a fan-out area, in which lead wires are provided. Each lead wire has a first end and a second end. There are signal traces each extending along a first direction provided in display area. The signal traces are electrically connected to first ends of lead wires. The convex area and concave area are arranged along a second direction. The second direction intersects first direction. A driving chip is included, which is a ball grid array package driving chip and is arranged in concave area where lead wires are away from first edge and electrically connected to second ends of lead wires.

Abstract: The present disclosure relates to a flexible display device, including a flexible substrate. The substrate includes a first portion, a second portion and a bending portion connecting the first portion to the second portion, wherein the flexible substrate has a thickness T. A plurality of display pixels is located at a side of the first portion of the flexible substrate. A supporting layer is located at a side of the flexible substrate facing away from the plurality of display pixels and includes a first supporting layer corresponding to the first portion and a second supporting area corresponding to the second portion. A thickness of the first supporting layer is T1, a thickness of the second supporting layer is T2, and a width of the bending portion is W, wherein W ≥ ( 2  T + T   1 + T   2 )  π 2 . Therefore, a narrow border is achieved, and the problem of interference during bending is alleviated.
