Abstract: A touch window according to an embodiment comprises: a substrate; a sensing electrode arranged on the substrate; and a reflection prevention layer arranged on the sensing electrode, wherein the reflection prevention layer comprises a first sub reflection prevention layer arranged on a first surface of the sensing electrode, a third sub reflection prevention layer arranged on a second surface, which lies opposite the first surface, and second sub reflection prevention layers arranged on both side surfaces, which connect the first and second surfaces, respectively. In addition, a touch window according to an embodiment comprises: a substrate; a base member comprising a pattern portion arranged on the substrate; a sensing electrode arranged inside the pattern portion; and a reflection prevention layer surrounding the sensing electrode, wherein the reflection prevention layer comprises a first sub reflection prevention layer arranged on the lower surface of the sensing electrode, second sub reflection prevention layers arranged on both side surfaces of the sensing electrode, and a third sub reflection prevention layer arranged on the upper surface of the sensing electrode, and the second sub reflection prevention layers comprise inclined surfaces, respectively. In addition, a touch window according to an embodiment comprises: a substrate; a sensing electrode on the substrate; a first sub reflection prevention layer arranged on a first surface of the sensing electrode; and a third sub reflection prevention layer arranged on a second surface of the sensing electrode, wherein at least one of the sensing electrode, the first sub reflection prevention layer, and the third sub reflection prevention layer has a side surface inclined at an acute angle of inclination with regard to a surface of the substrate.
