Abstract
A display panel and a manufacturing method thereof are provided. The display panel includes a flexible substrate, the flexible substrate includes a bending region and a non-bending region, and a thickness of the flexible substrate in the bending region is less than a thickness of the flexible substrate in the non-bending region.
Claims11
A display panel, comprising a flexible substrate, wherein the flexible substrate comprises a bending region and a non-bending region, and a thickness of the flexible substrate positioned in the bending region is less than a thickness of the flexible substrate positioned in the non-bending region;
- wherein a first groove is disposed on a surface of the flexible substrate, and the first groove is disposed corresponding to the bending region;
- and
- wherein a second groove is disposed on a surface of the flexible substrate opposite from the first groove, and the second groove is disposed corresponding to the bending region.
A method of manufacturing a display panel, comprising the following steps:
- providing a flexible substrate, wherein the flexible substrate comprises a bending region and a non-bending region;
- and
- performing a thinning process on the flexible substrate in the bending region so that a thickness of the flexible substrate in the bending region is less than a thickness of the flexible substrate in the non-bending region;
- wherein the flexible substrate comprises a first flexible layer, and an intermediate layer and a second flexible layer are sequentially disposed on the first flexible layer;
- wherein performing a thinning process on the flexible substrate in the bending region comprises the following steps:
- covering the first flexible layer and a surface of a side of the second flexible layer away from the intermediate layer in the non-bending region with a photoresist layer to expose the first flexible layer and the second flexible layer in the bending region;
- etching exposed the first flexible layer and the second flexible layer by an etching solution to thin thicknesses of the first flexible layer and the second flexible layer in the bending region;
- and
- removing the photoresist layer covered on the flexible substrate.
