Abstract
A chemically strengthened glass sheet in which a value of SB/(SA×t) is 5.0 mm−1 or more, where SA (MPa·μm) is an integrated value of a 5 compressive stress from a surface of the glass sheet to a depth of 10 μm, SB (MPa·μm) is an integrated value of a compressive stress from the depth of 10 μm to DOL which is a depth at which the compressive stress is zero, and t (mm) is a thickness of the glass sheet.
Claims10
A chemically strengthened glass sheet, wherein the chemically strengthened glass sheet has a value of SB/(SA×t) of 20.0 mm−1 or less,
- where SA (MPa·μm) is an integrated value of a compressive stress from a surface of the glass sheet to a depth of 10 μm,
- SB (MPa·μm) is an integrated value of a compressive stress from a depth of 10 μm to a DOL, the DOL being a depth at which a compressive stress is zero,
- t (mm) is a thickness of the glass sheet,
- SA is 1,000 MPa·μm to 4,000 MPa·μm, and
- SB is 22,000 MPa·μm or less.
