Abstract: A window includes a base region and a compressive stress region disposed on the base region. The compressive stress region includes Li+, Na+, and K+ ions. The compressive stress region includes a first compressive stress portion in which a concentration of the K+ ions decreases, a concentration of Na+ ions increases, and a concentration of the Li+ ions increases, from a surface of the window toward the base region. A second compressive stress portion is adjacent to the first compressive stress portion. In the second compressive stress portion, the concentration of the Na+ ion decreases and the concentration of the Li+ ion increases, from the first compressive stress portion toward the base region. The window thereby has a high surface compressive stress value and impact resistance.

Abstract: A jig for a cover window may include a lower jig and an upper jig on the lower jig. The lower jig may include a mounting portion, on which a cover window is configured to be disposed, and an exhausting portion adjacent to the mounting portion. The upper jig may include a cover unit, in which an opening exposing the mounting portion is defined, and a sidewall portion, coupled to the cover unit and enclosing the lower jig. The cover unit may be spaced apart from and overlapped with the exhausting portion.

Abstract: A glass substrate and a method for manufacturing the glass substrate are provided. The glass substrate may include a base glass including SiO2, Al2O3, and Li2O, and nanocrystals having an average diameter in a range from about 5 nm to about 10 nm, thereby exhibiting enhanced surface strength properties while maintaining good transmittance properties. The method may include a step of heat-treating a base glass, thereby providing a glass substrate having enhanced strength properties.
