摘要： The present invention relates to a window cover film and a flexible display panel including the same. More particularly, the present invention relates to a window cover film including a base layer and a hard coating layer, and a flexible display panel including the same. Since the window cover film of the present invention has high surface hardness, flexibility, the excellent bending properties, the window cover film may be restored to the original form without permanent deformation and/or damage of the hard coating layer and the window cover film even though a predetermined deformation is repeated.
