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.

Abstract: A molding method for a cover window includes: locally heating a peripheral portion of a glass substrate around a central portion of the glass substrate to a temperature of about 610° C. to about 670° C., forming a cover window by pressing the glass substrate, and annealing and cooling the cover window. Accordingly, a cover window in which each of edges has an outwardly convex curved surface through a glass substrate may be formed. In addition, the surface roughness of a cover window formed through a glass substrate may be improved.
