Abstract: A method of manufacturing a window includes preparing a base material layer, forming a first hard coating layer on the base material layer, and forming a second hard coating layer on the first hard coating layer. The forming of the second hard coating layer is performed in an environment having an oxygen concentration of about 0.01% to about 0.1%.

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.
