Glass sheet, accurately curved in two directions and having a compound curved surface, provides a non-cylindrical, non-spherical, smooth, continuous reflection image. When it is used as a door window pane, a smooth opening/closing by a simple mechanism is ensured, and a high degree of freedom in a moving direction is provided. This shape, although unable to be accurately formed by a conventional press molding method, can be achieved by a glass sheet bending method using a heat-resisting belt. |
