Abstract:
The purpose of the present invention is to provide a chemically strengthened glass having excellent transparency and strength and being scratch resistant. The present invention pertains to a chemically strengthened glass that: has a compressive stress layer on the surface thereof; has a visible light transmittance of at least 70% when the thickness thereof is converted to 0.8 mm; has a surface compressive stress of at least 600 MPa; has a compressive stress depth of at least 80 μm; and contains a β-spodumene.
