Abstract:
The present invention relates to a chemically strengthened glass, in which CT 1  and CT 5  satisfy CT 5 /CT 1 ≤0.85, the CT 1  satisfies CT 1 >−38.7×ln(t/1000)+48.2 [MPa] and an internal energy density rE satisfies rE≤23.3×t/1000+15 [kJ/m 2 ]. CS is a surface compressive stress value [MPa], σ (x) is a compressive stress value [MPa] at a position x in a depth direction, DOL is a compressive stress depth [μm], and t is a sheet thickness [μm].
