Manufacturing method for flexible display panel and flexible display panel comprising concave tapered organic layer

A manufacturing method for flexible display panel, comprising:

• providing an array substrate, the array substrate comprising a semiconductor layer, dividing the flexible display panel into a pixel area and a bending area, adjacent to each other, the pixel area comprising the semiconductor layer;
• disposing a second groove in the bending area, and the second groove forming a step structure in the array substrate, the step structure extending from inside of the array substrate towards direction opposite to inner wall of the second groove;
• filling the second groove with an organic material, and the organic material filling the second groove forming a concave tapered groove with flat surface of the array substrate;
• fabricating a source, a drain, and source/drain wiring on the array substrate, the source and the drain being connected to the semiconductor layer, the source/drain wiring covering the tapered groove;
• and
• disposing a first groove in the pixel area, patterns of the first groove and the second groove being formed by same mask, and then filling the first groove with an organic material.
