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 for manufacturing a display device according to an embodiment of the present invention includes providing a display substrate and an encapsulation substrate, each of which has a display area and a non-display area surrounding the display area thereon, forming a nanowire on the encapsulation substrate overlapping a sealing area defined as a partial area of the non-display area, and combining the encapsulation substrate and the display substrate with each other, wherein the forming of the nanowire includes irradiating a first laser, which is a ultrashort pulse laser, onto the encapsulation substrate overlapping the sealing area, and the combining of the encapsulation substrate and the display substrate with each other includes irradiating a second laser, which is a ultrashort pulse laser, onto the display substrate overlapping the sealing area.
