DISPLAY COVER GLASS AND DISPLAY
First Claim
1. A cover glass for use in transmitting the image displayed by an image display member while covering the image display member of a display, characterized:
- by being comprised of a glass comprising, converted based on the oxide and denoted as mol %;
60 to 75% of SiO2;
0 to 12% of Al2O3 (where the combined content of SiO2 and Al2O3 is 68% or greater);
0 to 10% of B2O3;
5 to 26% of Li2O and Na2O in total;
0 to 8% of K2O(where the combined content of Li2O, Na2O, and K2O is 26% or less);
0 to 18% of MgO, CaO, SrO, BaO, and ZnO in total;
0 to 5% of ZrO2, TiO2, and HfO2 in total;
0.1 to 3.5 weight percent of Sn oxides and Ce oxides based on the total amount of the glass components; and
a ratio of the content of Sn oxides to the combined content of Sn oxides and Ce oxides (content of Sn oxides/(content of Sn oxides+content of Ce oxides)) of 0.01 to 0.99;
the content of Sb oxides is 0.1% or less; and
by having a thickness of 1.0 mm or less.

Abstract
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.
