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 display device includes a base substrate, a first active pattern disposed on a base substrate, a second active pattern disposed on a first active pattern and including a material different from a material of a first active pattern, and an interlayer insulating layer disposed on a second active pattern and having Si—O bonds and Si—F bonds on a surface thereof, where a contact hole is defined through the interlayer insulating layer. The number of the Si—O bonds on the surface of the interlayer insulating layer is greater than the number of the Si—F bonds on the surface of the interlayer insulating layer.
