Abstract

The embodiment of the invention provides a flexible substrate and a flexible display device, and relates to the technical field of display. The flexible substrate comprises a flexible substrate and ametal support layer, wherein the metal support layer comprises a first region and a second region; the flexible substrate is stacked on the metal supporting layer, and the flexible substrate comprisesa third area corresponding to the first area and a fourth area corresponding to the second area; wherein the thickness of the first area is larger than that of the second area, and the thickness of the third area is smaller than that of the fourth area. According to the flexible substrate, the difference value of strain borne by different parts of the adhesive layer in the flexible display devicein the bending process can be reduced, so that the probability that bubbles are generated in the bending process of the adhesive layer is reduced, the anti-bending or anti-slip performance of the flexible display device is improved, and the service life of the flexible display device is prolonged.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a flexible substrate and a flexible display device. Background technique [0002] The display device is capable of displaying various images through a display screen to provide various information to a user. In recent years, flexible display devices developed based on flexible substrates have greatly improved user convenience because they are foldable, rollable or bendable like paper, and are easy to carry. [0003] In order to reduce the creases generated during the repeated folding process, the existing flexible display devices usually attach a metal support layer with better resilience on the bottom of the flexible substrate. In addition, in order to reduce the probability of the metal layer breaking when the metal supporting layer is bent with a smaller radius, the metal supporting layer usually adopts a patterned structure. [0004] However, due to the large ela...
