Claim 19:
20. A method for manufacturing a flexible display panel, comprising:
providing a flexible substrate, the flexible substrate comprising:
a display area;
a peripheral area, surrounding a periphery of the display area;
a welding area, on one side of the peripheral area distal to the display area; and
a bending area, between the peripheral area and the welding area, the bending area being configured to be bent along a bending axis, the bending area comprising a first edge, wherein the peripheral area comprises a peripheral transition area between the bending area and the welding area;
forming a barrier on the flexible substrate, the barrier being in the peripheral area and surrounding the periphery of the display area;
forming an organic insulation layer on the flexible substrate; and
forming a first groove in the organic insulation layer in the peripheral transition area, the first groove being on one side of the barrier distal to the display area and extending along a direction parallel to the bending axis, and the first groove being on one side of the first edge proximal to the display area,
wherein the first groove is formed through a patterning process performed on the organic insulation layer by using a dual-tone mask.
