Abstract: A method of manufacturing a reinforced cover window and a reinforced cover window manufactured thereby are proposed. The method includes a first step of forming a TPI layer on a base substrate, a second step of separating the TPI layer from the base substrate, a third step of forming an adhesive buffer layer on a glass substrate, and a fourth step of stacking the TPI layer on the adhesive buffer layer. This secures the TPI's unique pencil hardness of 4H to 6H while maintaining the unique aesthetic sense and touch feeling of the glass.
