Abstract:
The purpose of the present invention is to provide a chemically-strengthened glass exhibiting both surface strength and abrasion-resistant anti-fingerprint (AFP) properties. The present invention relates to a plate-shaped chemically-strengthened glass which has a compressive stress layer provided to a glass surface layer, a glass surface hydrogen concentration profile in a specific range, and a surface strength and abrasion-resistant anti-fingerprint (AFP) properties which are in specific ranges.
