摘要： Provided is a glass composition suitable for a glass substrate for a flat panel display such as a liquid crystal display. This glass composition has high thermal stability, and is substantially free of BaO but has a low devitrification temperature. It is suitable for the production of a glass substrate by a downdraw process. This glass composition contains, in terms of mass %; 54 to 62% of SiO2; 4 to 11% of B2O3; 15 to 20% of Al2O3; 2 to 5% of MgO; 0 to 7% of CaO; 0 to 13.5% of SrO; 0 to 1% of K2O; 0 to 1% of SnO2; and 0 to 0.2% of Fe2O3, and is substantially free of BaO. In this glass composition, the total content of alkaline earth metal oxides (MgO+CaO+SrO) is 10 to 18.5 mass %. The devitrification temperature of the glass composition is 1200° C. or lower.
