Abstract: A window for a display device includes a substrate has a pattern portion and a non-pattern portion. The pattern portion includes first groove patterns recessed from an upper surface of the substrate and second groove patterns recessed from a lower surface of the substrate and alternately arranged with the first groove patterns. The non-pattern portion is adjacent to the pattern portion. In addition, a plurality of first filling layers are disposed in the first groove patterns, and a second filling layer covers the first filling layers. A plurality of third filling layers are disposed in the second groove patterns, and a fourth filling layer covers the third filling layers. A height of the pattern portion is less than a height of the non-pattern portion.
