Abstract
A method of manufacturing a composite film layer applicable to a flexible display panel includes providing a transparent substrate film; forming a deformed state of the transparent substrate film by applying a predetermined degree of tensile stress to the transparent substrate film; forming a hardened layer on the transparent substrate film in the deformed state; and releasing the tensile stress from the transparent substrate film in the deformed state to enable a molecular chain in the hardened layer to contract.
