Specifically, provided is a window cover film protecting a surface of a display device, the window cover film including a protective film formed on a base layer or a hard coating layer of a hard coating film having the base layer and the hard coating layer, and having no problem that the window cover film cannot be used as a display window cover film because a part of the protective film is not peeled off due to static electricity generated in the protective film, the base layer, or the hard coating layer when the protective film is peeled off, and the protective film remains on the base layer or a hard coating layer or the hard coating layer is partially or entirely peeled off.
