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.
