Abstract

The embodiments of the disclosure disclose a flexible substrate, a fabrication method thereof, and a flexible display apparatus. The flexible substrate includes a first organic layer and an inorganic buffer layer stacked together. The first organic layer and the inorganic buffer layer form an organic-inorganic composite structure. The expansion coefficient of the flexible substrate provided by the embodiment of the present disclosure is more matched with that of the rigid auxiliary substrate, so as to reduce the risk of warping of the rigid auxiliary substrate and then improve the process accuracy when fabricating the display device.
