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: An ion generator includes a circuit board through which a high voltage flows; a high-voltage electrode to which a high voltage is applied through contact with the circuit; a ground electrode grounded through contact with the circuit and spaced apart from the high-voltage electrode; and a holder kit in which a first insertion groove, into which the high-voltage electrode is inserted, and a second insertion groove, which is spaced apart from the first insertion groove and into which the ground electrode is inserted, are formed in the vertical direction, and thus a stable uniform electric field can be continuously formed through the integration of the high-voltage electrode and the ground electrode by using the holder kit, so that the lifespan of an electrode can be improved and the occurrence of discharge noise can be suppressed.

Abstract: A cover window of a display device includes: a transparent layer; a light blocking layer disposed on the transparent layer, the light blocking layer defining an opening therein, the opening exposing a portion of the transparent layer which corresponds to a sensor of the display device; and an anti-pollution layer disposed corresponding to the portion of the transparent layer which corresponds to the sensor of the display device and is exposed by the opening. The anti-pollution layer has a surface energy lower than each of a surface energy of the transparent layer and a surface energy of the light blocking layer.
