Moreover, since the hard coating 20 is not disposed on the flexible substrate 10 corresponding to the bending area BA, the bending performance of the bending area BA of the cover plate 100 can be ensured.
In some alternative embodiments, the flexible substrate 10 may be a polymer film with good bending properties. The material of the flexible substrate 10 may be, for example, one or more of Polyimide (PI), poly (terephthalic acid), Polyethylene naphthalate (PEN), Polymethyl methacrylate (PMMA), polyurethane, and aramid. Alternatively, the thickness of the flexible substrate may be 50 μm to 150 μm, for example, 60 μm, 70 μm, 90 μm, 100 μm, 120 μm, 130 μm, or the like.
