Patent abstract
The present invention relates to a chemically strengthened glass, in which CT1 and CT5 satisfy CT5/CT1≤0.85, the CT1 satisfies CT1>−38.7×ln(t/1000)+48.2 [MPa] and an internal energy density rE satisfies rE≤23.3×t/1000+15 [kJ/m2]. 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].
