Glasses for flat panel displays

Glasses are disclosed which are used to produce substrate in flat panel display devices. The glasses exhibit a density less than about 2.45 gm/cm and a liquidus viscosity greater than about 200,00 poises, the glass consisting essentially of the following composition, expressed in terms of mol percen...

Zusammenfassung:	Glasses are disclosed which are used to produce substrate in flat panel display devices. The glasses exhibit a density less than about 2.45 gm/cm and a liquidus viscosity greater than about 200,00 poises, the glass consisting essentially of the following composition, expressed in terms of mol percent on an oxide basis: 65-75 SiO2, 7-13 Al2O3, 5-15 B2O3, 0-3 MgO, 5-15 CaO, 0-5 SrO, and essentially free of BaO. The glasses also exhibit a strain point exceeding 650 DEG C.
