A method of manufacturing a window may include steps of: cutting a window having a uniform thickness of about 20 μm to about 100 μm; and polishing a cut surface of the window with a polishing pad having a smaller elastic modulus than the elastic modulus of the window while supplying slurry to the cut surface of the window. One objective of the present invention is to provide the method of manufacturing a window for improving an impact strength of the window. 윈도우의 제조 방법은 약 20 ㎛ 내지 약 100 ㎛의 균일한 두께를 가지는 윈도우를 절단하는 단계 그리고 윈도우의 절단면에 슬러리를 공급하면서 윈도우의 탄성 계수(elastic modulus)보다 작은 탄성 계수를 가지는 연마 패드로 윈도우의 절단면을 연마하는 단계를 포함할 수 있다.
