摘要:
Disclosed are a thin-sheet cover glass that is high in quality and has high mechanical strength, and a display equipped with the aforementioned cover glass. The cover glass is used to cover the image display unit of a display and to make images displayed by the aforementioned image display unit opaque. The cover glass is formed from a glass that comprises, in an oxide base conversion indicated in mol %, 60 to 75% SiO2, 0 to 12% Al2O3 (provided that the total content of SiO2 and Al2O3 is 68% or more), 0 to 10% B2O3, 5 to 26% Li2O and Na2O in total, 0 to 8% K2O (provided that the total content of Li2O, Na2O, and K2O is 26% or less), 0 to 18% MgO, CaO, SrO, BaO in total, and ZnO, and 0 to 5% ZrO2, TiO2, and HfO2 in total, as well as a total of 0.1 to 3.5 mass % of an Sn oxide and a Ce oxide relative to the total mass, wherein (Sn oxide content/(Sn oxide content+Ce oxide content)) is 0.01 to 0.99, and the content of an Sb oxide is 0 to 0.1%; and has a plate thickness of no more than 1.0 mm.
