Abstract
Official abstract text for this publication.
Described herein are alkali-free, boroalumino silicate glasses exhibiting desirable physical and chemical properties for use as substrates in flat panel display devices, such as, active matrix liquid crystal displays (AMLCDs) and active matrix organic light emitting diode displays (AMOLEDs). In accordance with certain of its aspects, the glasses possess good dimensional stability as a function of temperature. The glasses comprise in mol percent on an oxide basis: 70-74.5 SiO2, 10.5-13.5 AL2O3, 0-2.5 B2O3, 3-7 MgO, 3-7 CaO, 0-4 SrO, 1.5-6 BaO, 0-0.3 SnO2, 0-03 CeO2, 0-0.5 As2O3, 0-0.5 Sb2O3, 0.01-0.08 Fe2O3 and F+Cl+Br RO/Al2O3 1.7 and 0.2 MgO/RO 0.45, RO being the sum of MgO, BaO, SrO and CaO.
