Disclosed are alkali-free glasses having a liquidus viscosity of greater than or equal to about 90,000 poises, said glass comprising SiO 2 Al 2 O 3 , B 2 O 3 , MgO, CaO, and SrO such that, in mole percent on an oxide basis: 64 ‰¤ SiO 2 ‰¤ 68.2; 11 ‰¤ Al 2 O 3 ‰¤ 13.5; 5 ‰¤ B 2 O 3 ‰¤ 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. |
