The present invention discloses a substrate glass and a glass composition, wherein said glass composition comprises: Si02 from about 63.3 to about 71.3 mole %; Al203 from about 8.1 to about 12.1 mole %; B203 from about 6.7 to about 12.7 mole %; CaO from about 8 to 8.6 mole %; MgO from about 3 to 3.5 mole % and Cs20 from about 0.001 to about 0.9 mole %; wherein inclusion of the alkali metal Cs20 decreases the melting point of the substrate glass composition and at the same time as the cesium has a high radii as compared with other alkali metals, has very low mobility and thereby does not diffuse out and interfere with the TFT operation. |
