Abstract: 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.

Abstract: Provided are a polyimide-based film having excellent visibility, a film for a cover window, and a display device including the same.

Abstract: Provided is a hard coating film. The hard coating film includes a base layer and a hard coating layer disposed on the base layer and having a pencil hardness of 4H or higher. A surface elongation at break of the hard coating film falls within a predetermined range, as measured by a certain method. The hard coating film shows excellent durability under high-temperature/high-humidity conditions, has no microcracks formed after repeated folding, and shows excellent pencil hardness.

Abstract: An optical multilayer structure comprising a substrate layer; and a hard coating layer formed on one surface of the substrate layer, wherein the optical multilayer structure has a water contact angle of an outermost layer in accordance with ASTM D5964 of 105° or less. The optical multilayer structure according to one embodiment has improved adhesion with a different kind of film due to high surface energy of an outermost layer to have both excellent durability and excellent wear resistance, and thus, may be usefully applied to a window cover film or a flexible display panel.
