Claim 9:
10. A touch panel, comprising: a transparent substrate, a touch structure disposed on the transparent substrate, and a protective film; wherein
the protective film is configured to be attached to the transparent substrate to protect the transparent substrate from being damaged, and comprises a transparent substrate layer and a transparent hardened layer covering a surface of the transparent substrate layer, wherein the transparent hardened layer comprises a first region covering a middle portion of the transparent substrate layer and a second region covering an edge of the transparent substrate layer, a hardness of the first region being greater than a hardness of the second region; and
the protective film is disposed on one side of the transparent substrate, and the touch structure is disposed on the other side of the transparent substrate; and
wherein the transparent hardened layer is formed from a photocurable coating on the surface of the transparent substrate layer, and
wherein the photocurable coating is cured by light irradiation, and the light irradiation duration of the photocurable coating disposed on the middle portion of the transparent substrate layer is longer than a light irradiation duration of the photocurable coating disposed at the edge of the transparent substrate layer.
