显示器用玻璃基板和显示器
Abstract:
本发明涉及一种显示器用玻璃基板，所述玻璃基板由具有轻质、高精练性同时减轻环境负担的玻璃形成，所述玻璃包括质量％的如下组分，50至70％的SiO2，5至18％的B2O3，10至25％的Al2O3，0至10％的MgO，0至20％的CaO，0至20％的SrO，0至10％的BaO，5至20％的RO(其中，R是至少一种选自Mg、Ca、Sr和Ba的元素)，和大于0.20％但不超过2.0％的R’2O(其中，R’是至少一种选自Li、Na和K的元素)，并且所述玻璃包含0.05至1.5质量％的在熔融玻璃中化合价会发生变化的金属的氧化物，并且基本上不含As2O3、Sb2O3和PbO。
Abstract(English):

The present invention provides a glass substrate for a display, which is formed of a glass having a light weight and having high refining with decreasing environmental burdens, the glass comprising, by mass %, 50 to 70% of SiO2, 5 to 18% of B2O3, 10 to 25% of Al2O3, 0 to 10% of MgO, 0 to 20% of CaO, 0 to 20% of SrO, 0 to 10% of BaO, 5 to 20% of RO (in which R is at least one member selected from the group consisting of Mg, Ca, Sr and Ba), and over 0.20% but not more than 2.0% of R'2O (in which R' is at least one member selected from the group consisting of Li, Na and K), and containing, by mass %, 0.05 to 1.5% of oxide of metal that changes in valence number in a molten glass, and substantially containing none of As2O3, Sb2O3 and PbO.
