Original Abstract Submitted
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.
