METHOD OF MANUFACTURING A GLASS SUBSTRATE FOR USE AS A COVER GLASS FOR A MOBILE ELECTRONIC DEVICE, GLASS SUBSTRATE FOR USE AS A COVER GLASS FOR A MOBILE ELECTRONIC DEVICE, AND MOBILE ELECTRONIC DEVICE

摘要

A glass substrate manufacturing method of this invention includes a first chemical strengthening process for chemically strengthening a plate-like glass member by ion exchange, a cutting process for cutting the plate-like glass member into small pieces after the first chemical strengthening process, thereby obtaining a plurality of glass substrates, and a second chemical strengthening process for chemically strengthening the glass substrates by ion exchange after the cutting process.
