Abstract
A protection film according to an embodiment implements a very low reflectivity through a multilayer structure of which the refractive index is controlled and does not cause whitening and cracking to occur even in the case of frequent bending or folding thereof. Accordingly, the protection film is applied to a flexible display device, and especially to a cover of a foldable display device, thereby showing excellent optical and mechanical characteristics.
