Method of manufacturing glass plate having curved surface shape, and glass plate having a curved surface shape

Abstract

Provided is a method that can manufacture a glass plate having a curved surface shape with high surface accuracy even without polishing the surface after forming and a glass plate manufactured by the method. The method of manufacturing a glass plate having a curved surface shape includes the steps of: preparing an original glass plate, a forming die () including a recess () corresponding to the curved surface shape, and a forming tool () operable to press the original glass plate (); placing the original glass plate () on the recess () in the forming die (); heating the original glass plate () and the forming die (); maintaining a temperature of a surface of the recess () in the forming die at a temperature lower than a temperature of the original glass plate (); and giving the original glass plate () the curved surface shape by pressing the heated original glass plate () with the forming tool () to deform the original glass plate () while bringing the original glass plate () into contact with the surface of the recess ().
