A constitution of environment-friendly glass for TFT-LCD is provided, which is employed in Thin Film Transistor Liquid Crystal Display, the constituents consist, expressed in terms of weight % on the oxide basis, of from 59 to 63 wt. % of SiO2; from 13 to 17 wt. % of Al2O3; from 7 to 14 wt. % of B2O3; from 0.1 to 3 wt. % of BaO; from 0.5 to 3.5 wt. % of MgO; from 7 to 11 wt. % of CaO; from 0.2 to 6 wt. % of SrO; and from 0.05 to 0.4 wt. % of SnO2. The constitution then can be melted to form environment-friendly glass for TFT-LCD with high stiffness. The environment-friendly glass for TFT-LCD is formed to allow increase in chemical resistance, so as to solve the conventional problems of insufficiency in both strength and hardness and of inclusion of environment-unfriendly constituents as As2O3 or Sb2O3. |
