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.
