An alkali-free glass for flat panel display consists of, by weight, 54-68% SiO2, 10.8-17.1% Al2O3, 7.6-12.5% B2O3, 0.2-1.8% MgO, 4.2-8% CaO, 0.6-7.1% SrO, 0.1-5% BaO, 0.2-1% ZnO, 0.01-1.54% ZrO2 and 0.1-1.3% SnO+SnO2. The boroaluminosilicate glass of the present invention does not contain As and Sb which contribute to serious environmental pollution. The quality of the glass is improved by the specific process which reduces the content of the gas inclusions in the glass.
