A display panel, comprising:
- an island region;
- a chain region connected to the island region and extending to an outer side of the island region;
- an array substrate provided with at least one subpixel and comprising a first organic layer;
- a plurality of undercut structures defined on the array substrate and recessed in the first organic layer of the array substrate;
- and
- an encapsulation layer covering the array substrate and filled in the undercut structures;
- wherein the undercut structures comprise:
- a first undercut structure defined in the island region and surrounding the subpixel;
- and
- a second undercut structure defined in the chain region.
A manufacturing method of a display panel, comprising steps of:
- forming an array substrate, wherein a first organic layer is formed on a flexible base layer, the array substrate comprises an island region and a chain region, a subpixel is formed in the island region, a connecting circuit is formed in the chain region, and the chain region is connected to the island region and extends to an outer side of the island region;
- defining a plurality of undercut structures, wherein the undercut structures comprise a first undercut structure and a second undercut structure, the first undercut structure is positioned in the island region, and the second undercut structure is positioned in the chain region;
- and
- forming an encapsulation layer covering the undercut structures and the array substrate.
