COVER WINDOW AND DISALY DEVICE INCLUDING THE SAME

摘要

The present invention relates to a cover window in which a copolymer having different contents of a low-stiffness monomer and a high-stiffness monomer is synthesized in a first region and a second region, and a foldable display device including the same. Since the contents of the low-stiffness monomers and the high-stiffness monomers in the first region and the second region differ, it is possible to realize the foldable characteristic around the first region. The contents of the low-stiffness monomer and the high-stiffness monomer are different in the first region and the second region, but the first region and the second region are composed of the same copolymer. Therefore, since the refractive indexes of the first and second regions are the same, no visibility due to the refractive index difference occurs at the interface between the first region and the second region. Therefore, even when the cover window of the present invention is applied to the surface of the display device, a beautiful appearance free from visual distortion can be secured. In addition, a cover window including a plurality of regions having the same refractive index and different stiffness or hardness covers the front and side surfaces of the display panel, thereby providing a display device having a beautiful appearance without detachment of the visibility and the cover window.
