Display panel and manufacturing method thereof

A manufacturing method of a display panel, the display panel comprising a first folding region and two non-folding regions located at two sides of the first folding region, the manufacturing method of the display panel comprising following steps:

• providing a bonding layer, wherein the bonding layer comprises a bending section arranged corresponding to the first folding region and a first section and a second section arranged corresponding to the non-folding regions, and a bending curvature of the bending section is a first curvature;
• providing a first film layer, and attaching the first film layer to a first surface of the bonding layer to form a composite film layer;
• and
• setting the composite film layer in a flat state, and forming a second film layer on a second surface of the bonding layer away from the first film layer, wherein a curvature formed by the composite film layer and the second film layer is a second curvature, and the first curvature is greater than the second curvature;
• wherein when the display panel is in a bent state, first tangential forces of the first film layer exerted on the first surface and second tangential forces of the second film layer exerted on the second surface point to a center of the first folding region.
