    • A glass substrate for a display, which is formed of a glass having a light weight and having high refinability 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.
    • 一种显示器用玻璃基板,其由重量轻且具有降低的环境负荷的高可熔性的玻璃形成,所述玻璃以质量%计含有50〜70%的SiO 2,5〜18%的B 2 O 3,10〜 25%的Al 2 O 3,0〜10%的MgO,0〜20%的CaO,0〜20%的SrO,0〜10%的BaO,5〜20%的RO(其中R为选自 由Mg,Ca,Sr和Ba组成的组)和超过0.20%但不超过2.0%的R'2O(其中R'为选自Li,Na和K中的至少一种), 并且以质量%计含有熔融玻璃中价数变化的金属氧化物的0.05〜1.5%,并且基本上不含有As 2 O 3,Sb 2 O 3和PbO。
