Disclosed are alkali-free glasses having a liquidus viscosity of greater than or equal to about 90,000 poises, said glass comprising SiO2, Al2O3, B2O3, MgO, CaO, and SrO such that, in mole percent on an oxide basis: 64@SiO2@68.2; 11@Al2O3@13.5; 5@B2O3@9; 2@MgO@9; 3@CaO@9; and 1@SrO@5. The glasses can be used to make a display glass substrates, such as thin film transistor (TFT) display glass substrates for use in active matrix liquid crystal display devices (AMLCDs) and other flat panel display devices. |
