Abstract: A window includes a folding portion foldable with respect to an imaginary folding axis extending in a first direction, a first non-folding portion, and a second non-folding portion spaced apart from the first non-folding portion in a second direction perpendicular to the first direction with the folding portion interposed therebetween. The folding portion includes a base portion and a plurality of protrusion portions disposed on the base portion and spaced apart from each other in the second direction. A width, in the first direction, of the folding portion is smaller than a width, in the first direction, of each of the first non-folding portion and the second non-folding portion.

Abstract: A method for manufacturing a glass window. The glass window includes a folding area folded with respect to a folding axis and a non-folding area adjacent to the folding area. The method for manufacturing the glass window includes forming a pattern glass including a pattern part and a non-pattern part adjacent to the pattern part, the pattern part including first groove patterns in a first surface and corresponding to the folding area and a non-pattern part adjacent to the pattern part and corresponding to the non-folding area, and forming a filling layer on the pattern part. The forming of the filling layer includes initial filling of a filling resin into the groove patterns, and additional filling of the filling resin into the outermost groove patterns that are farthest from the folding axis among the groove patterns.
