Abstract
Provided is an antistatic polyimide-based film. More particularly, as an antistatic polyimide-based film for a window cover for protecting a surface of a display device, a window cover film having a protective film formed on the polyimide-based film provides an improvement to a problem of not being used as a film for a display window cover because a portion of the protective film remains on a base layer or a hard coating layer without being peeled off due to static electricity in the protective film or the base layer, or a hard coating layer, or the hard coating layer is peeled off with some or all of the protective film when the protective film is peeled off.
