Abstract

The invention relates to a flexible substrate, a manufacturing method thereof, a display screen and a display device. The flexible substrate includes: a first flexible substrate; a barrier layer formed on the first flexible substrate, the surface of the barrier layer away from the first flexible substrate has several first protrusions, and a first protrusion is formed between adjacent first protrusions. The concave part, the cross-sectional area of ​​the top end of the first convex part away from the first flexible substrate along the surface parallel to the first flexible substrate is smaller than the cross-sectional area of ​​the bottom end of the first convex part close to the first flexible substrate along the surface parallel to the first flexible substrate and a second flexible substrate formed on the barrier layer, the surface of the second flexible substrate opposite to the first convex portion has several second convex portions, and a gap for accommodating the first convex portion is formed between adjacent second convex portions The second concave part and the second convex part are matched with the first concave part. When the flexible substrate of the present invention is impacted by external force, display failure can be avoided. In addition, it also relates to a display screen and a display device comprising the above-mentioned flexible substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible substrate, a manufacturing method thereof, a display screen and a display device. Background technique [0002] With the development of display technology, consumers' demand for high-quality display screens is increasing. However, when the traditional display screen is impacted by an external force, it is easy to cause display failure, which is not conducive to application. Contents of the invention [0003] Based on this, it is necessary to address the problem of how to avoid display failure caused by external force impact, and provide a flexible substrate capable of avoiding display failure due to external force impact, a manufacturing method thereof, a display screen, and a display device. [0004] A kind of flexible substrate, described flexible substrate comprises: [0005] a first flexible substrate; [0006] a barrier layer formed on the first flexible sub...
