Laminated glass

摘要

The present invention provides a laminated glass. Each single glass sheet has a thickness of 1.5 to 3.2 mm and is subjected to a bending process. At least one of the glass sheets is a semi-tempered glass sheet, which is also called a heat-strengthened glass sheet. The heat-strengthened glass sheet has a plane residual stress distribution where the plane residual stress is a compressive stress at an edge of a peripheral portion of the glass sheet. The plane residual stress changes monotonically from the compressive stress at the edge of the peripheral portion to a tensile stress in a central portion of the glass sheet substantially throughout the peripheral portion of the single glass sheet.
