Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

The present invention provides glass for cover glass for large display devices, said glass: having a surface compressive stress comparable to that when chemical strengthening has been conducted at a low temperature even when ion exchange has been conducted at a high temperature; undergoing little change in compressive stress even when a temperature change has occurred; and providing excellent productivity. The present invention pertains to a cover glass for flat panel displays obtained by chemically strengthening glass, and the molar ratio of Na20, Al2O3, MgO and ZrO2 in the glass before chemical strengthening satisfies formula (1). (Na20/2)/(Al2O3/2 + MgO + ZrO2) ≤ 0.85...formula (1)
