Abstract: A method for manufacturing the window includes providing an initial window having a first compressive stress value and cleaning the initial window to provide a window having a second compressive stress value. The cleaning of the initial window includes acid cleaning the initial window by using acid, and alkali cleaning the initial window by using alkali after the acid cleaning. A linear relational expression is modeled between a difference between the first and second compressive stress values and a temperature and a holding time in the acid cleaning.

Abstract: A method of manufacturing a window includes: preparing a glass substrate laminate which includes preparing a base substrate, alternately disposing glass substrates and adhesive layers on the base substrate, and disposing a cover substrate on the glass substrates and the adhesive layers alternately disposed; and cutting the glass substrate laminate, where the adhesive layers include a potassium nitrate (KNO3) particle and an adhesive resin. This method makes it possible to effectively manufacture an ultra-thin glass substrate used for a window.
