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 ().

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

Provided is a mobile-display cover glass less susceptible to damage from impact caused upon dropping of a mobile display. A mobile-display cover glass () is a mobile-display cover glass configured to cover a display region () and at least a portion of a side surface () of a mobile display (). The mobile-display cover glass () includes a flat sheet-like front portion () and a side portion (). The front portion () is configured to be disposed in front of the display region (). The front portion () extends in a first direction and a second direction perpendicular to the first direction. The side portion () is configured to be disposed lateral to the mobile display (). The side portion () includes a bent portion (). The bent portion () bends backward from one end of the front portion () in the first direction. A corner () of the side portion () has a rounded shape.

Provided is a method capable of producing a glass sheet with a bent portion in which a flattened portion has high flatness and high smoothness. A flat glass sheetis radiationally heated with a first portionthereof held between first and second heat-insulating members. And then, a second portionof the flat glass sheetnot held between the first and second heat-insulating membersis bent.
