Abstract
A flexible protective film is provided and is used to protect a curved display. The flexible protective film includes a substrate layer (10) and a flexible layer (20) laminated on the substrate layer (10). The flexible layer (20) is formed after a liquid-phase flexible material is laminated on a surface of the substrate layer (10) through solidification. The flexible layer (20) of the flexible protective film is directly formed on the substrate layer (10) to reduce internal stress of the flexible protective film, thereby increasing an adhesive force of the flexible protective film.
