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, an inorganic buffer layer, and a second organic layer. The inorganic buffer layer is between the first organic layer and the second organic layer. The second organic layer includes inorganic nano-particles. 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.
