Patent ID: 6852658

Claim:
A glass substrate for a flat panel liquid-crystal display, such as for a laptop computer, the flat panel liquid-crystal display including a twisted nematic display, a supertwisted nematic display, an active matrix liquid-crystal display, a thin film transistor display, and a plasma addressed liquid-crystal display, said substrate comprising: an alkali-free aluminoborosilicate glass; said glass having a coefficient of thermal expansion α 20/300 of between 2.8×10 −6 /K and 3.8×10 −6 /K; said glass having the composition (in % by weight, based on oxide): SiO 2 >58-64.5 B 2 O 3 >6-10.5 Al 2 O 3 >18-24 MgO 0-<3 CaO 1-<8 SrO 0.1-1.5 BaO >5-8 with SrO + BaO ≦8.5 with MgO + CaO + SrO + BaO 8-18 ZnO 0-<2; said glass being configured to be resistant to thermal shock; said glass being configured to have a high transparency over a broad spectral range in the visible and ultra violet ranges; and said glass being configured to be free of bubbles, knots, inclusions, streaks, and surface undulations.
