摘要：Provided is a tempered glass sheet having a compression stress layer in asurface thereof, comprising, as a glass composition expressed in mass % in terms ofoxides, 50 to 70% of SiO, 5 to 20% of AlO, 0 to 5% of BO, 8 to 18% of NaO, 2 to 9% of KO,and 30 to 1,500 ppm of FeO, and having a spectral transmittance in terms of a thickness
of 1.0 mm at a wavelength of 400 to 700 nm of 85% or more, a chromaticity x of 0.3095 to0.3120 in xy chromaticity coordinates (illuminant C, in terms of a thickness of 1 mm), and achromaticity y of 0.3160 to 0.3180 in xy chromaticity coordinates (illuminant C, in terms ofa thickness of 1 mm).
