A composite film may include a first transparent substrate and a first anti-reflective coating overlying a first surface of the first transparent substrate. The first anti-reflective coating may include a first UV curable acrylate binder, a photo initiator component, and silica nanoparticles dispersed within the first anti-reflective coating. The first anti-reflective coating may further include a ratio AC1.sub.SiO2/AC1.sub.B of at least about 0.01 and not greater than about 1.3. The composite film may further have a VLT of at least about 93.0% and a haze value of not greater than about 3%.

A flexible window stack structure includes a substrate, a first hard coating layer formed on a surface of the substrate and a second hard coating layer formed on an opposite surface of the substrate. The first hard coating layer has a curing contraction greater than that of the second hard coating layer, and the second hard coating layer is disposed at an elongated side when the window stack structure is folded. Cracks may be prevented by a curl property of the first hard coating layer when being bent.
