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.
