Abstract
An array substrate includes a base substrate, at least one inorganic film layer, and at least one organic soft film layer. The organic soft film layer is disposed on a side of the inorganic film layer adjacent to the base substrate, and a side surface of the organic soft film layer adjacent to the inorganic film layer has a wavy shape. By using the inorganic film layer to generate a compressive stress on the organic soft film layer, the organic soft film layer is wavy, and the inorganic film layer is also wavy, which reduces the stress concentration of the panel when bending, and improves the bending performance of the flexible display panel.

An array substrate, comprising:
- a base substrate;
- at least one inorganic film layer disposed on the base substrate;
- and
- at least one organic soft film layer disposed on a side of the inorganic film layer adjacent to the base substrate;
- wherein a side surface of the organic soft film layer adjacent to the inorganic film layer has a wavy shape, and the organic soft film layer is made of polyhexamethyldisiloxane or polyethylene glycol aluminum.
A manufacturing method of an array substrate, comprising the following steps:
- step S10:
- providing a base substrate, and forming an organic soft film layer on the base substrate;
- and
- step S20:
- forming an inorganic film layer on a surface of the organic soft film layer, wherein the inorganic film layer generates a compressive stress on the organic soft film layer, such that the compressive stress forms the organic soft film layer in a wavy shape, wherein the organic soft film layer is made of polyhexamethyldisiloxane or polyethylene glycol aluminum.
A flexible display panel, comprising:
- an array substrate comprising a base substrate, an organic soft film layer, and an inorganic film layer which are sequentially disposed;
- a light emitting layer disposed on the array substrate;
- and
- an encapsulation layer disposed on the light emitting layer;
- wherein a side surface of the organic soft film layer adjacent to the inorganic film layer has a wavy shape, and the organic soft film layer is made of polyhexamethyldisiloxane or polyethylene glycol aluminum.
