Abstract: A glass article includes a central layer including a first crystalline phase having a first coefficient of thermal expansion and a surface layer surrounding an entirety of the central layer and including a second crystalline phase having a second coefficient of thermal expansion smaller than the first coefficient of thermal expansion. Accordingly, the strength of the glass article may be improved.

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.

Abstract: A cover window may include a polymer film, a printing layer disposed below the polymer film, and a hard coating layer. The hard coating layer may include a first portion disposed on a top surface of the polymer film and overlapping the polymer film, a second portion disposed on a bottom surface of the printing layer and overlapping the printing layer, and a third portion disposed between the first portion and the second portion. An area of the second portion may be smaller than an area of the printing layer in plan view. The cover window including the hard coating layer may have an improved mechanical robustness property and an improved reliability property.
