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 Kions. The compressive stress region includes a first compressive stress portion in which a concentration of the Kions decreases, a concentration of Naions increases, and a concentration of the Liions 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 Naion decreases and the concentration of the Liion increases, from the first compressive stress portion toward the base region. The window thereby has a high surface compressive stress value and impact resistance.
