Abstract: Methods of manufacturing a curved cover window of the disclosure prevent or reduce damage to a window substrate of the curved cover window. Methods include manufacturing methods in which a hard coating layer is formed on a window substrate, and optionally molding the window substrate on which the coating layer is formed in a manner as to minimize or reduce breaking or damage to the window substrate. By using a hard coating layer which is harder than the window substrate and which may include a first polycarbonate layer, a second polymethyl methacrylate layer, and polysilsesquioxane; and thermally molding the window substrate and hard coating layer at a temperature of about 120° C. to about 130° C. and for about three minutes to about five minutes; rupture of the window substrate during the molding process can be reduced.

Abstract: A method of manufacturing a window for a display apparatus according to the present invention includes: providing, on a stage, a substrate including a foldable part bending around a folding axis extending in a first direction, and forming a groove on the foldable part. The forming the groove includes: grinding the foldable part by using a first machining wheel; grinding the foldable part by using a second machining wheel; and machining the foldable part by using a polishing wheel. The groove has at least one radius of curvature. The first machining wheel includes first abrasive grains, and the second machining wheel includes second abrasive grains less in size than the first abrasive grains.
