Abstract: A curved glass manufacturing method includes: successively stacking a lower mold, flat glass, and an upper mold, thereby forming a mold assembly; moving the mold assembly to a first chamber and then heating the same; moving the mold assembly from the first chamber to a second chamber and then pressurizing the upper mold so as to move the upper mold downward, thereby molding the flat glass in a curved shape; moving the mold assembly from the second chamber to a third chamber and then slowly cooling the molded glass; and moving the mold assembly from the third chamber to a fourth chamber and then cooling the molded glass. An elastic member is arranged between the lower mold and the upper mold and configured to define a space between the upper mold and the flat glass, and the elastic member is compressed when the upper mold is pressurized.
