Abstract:
A chemically strengthened glass obtained by chemically strengthening a lithium-containing aluminosilicate glass, when representing a sheet thickness of the chemically strengthened glass by t (μm) and an internal stress at a depth x (μm) from a surface of the chemically strengthened glass by σ(x) (MPa), has a value of a ratio C=rE/rElimit being greater than or equal to 0.7 and less than 1.0 where rE (kJ/m2) is calculated from Expression (3) described above and rElimit=16×t/1000+3.
