    Abstract: The present disclosure relates to a cover window and a flexible display device including the same. The cover window according to an exemplary embodiment of the present disclosure includes a first layer having a first modulus, a second layer disposed on the first layer and having a second modulus smaller than the first modulus, and a third layer disposed on the second layer and having a third modulus equal to or larger than the first modulus, and in which the third layer includes a nanoparticle-polyurethane complex in which polyurethane is bonded with nanoparticles by a covalent bond. Therefore, the cover window of the present disclosure provides effects that the folding and rolling are possible with excellent surface characteristic and the restorability against the pressing and excellent optical property.

    Abstract: A foldable display device is disclosed. The foldable display device includes a display panel including a folding area and a non-folding area, a back plate unit, and a plurality of adhesive layers disposed between the display panel and the back plate unit and between the back plate units. Some of the plurality of adhesive layers includes a first adhesive part and a second adhesive part having different adhesiveness. Therefore, an adhesiveness of the plurality of adhesive layers is controlled to reduce the stress generated at the time of folding the foldable display device.
