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 heat radiating member includes bismuth. The heat radiating member defines a plurality of holes therein, and the plurality of holes is separated from each other in a plan view. Separation distances between the plurality of holes in the plan view each are more than about 40 nm and equal to or less than about 150 nm.

Abstract: A display device includes a substrate, a plurality of pixel columns, and a lighting test circuit unit. The lighting test circuit unit is disposed in a non-display area on the substrate, includes a plurality of lighting test transistors, and provides a lighting test voltage to the pixel columns. Each of the lighting test transistors includes an active pattern including a source area, a drain area, and a channel area, a gate electrode disposed in the channel area, an interlayer insulating layer including a first contact hole spaced apart from a first side of the gate electrode by about 7 um or more, and a source electrode contacting the source area of the active pattern through the first contact hole.
