    Abstract: Provided is a cover window. The cover window includes a substrate layer. The cover window further includes a hard-coating layer on the substrate layer. The cover window further includes a protective film disposed on the hard-coating layer and including a base film and a plurality of protrusions protruding from the base film. The cover window further includes an adhesive layer disposed on surfaces of the plurality of protrusions and bonding the hard-coating layer and the protective film. The protective film includes a first area and second areas disposed on both sides of the first area. The plurality of protrusions are disposed in the first area. The plurality of protrusions have a shape in which the protrusions disposed on one side and the protrusions disposed on the other side are symmetrical to each other with respect to a central line of the first area.
