Glass substrate and method for manufactring the same |
摘要 |
A glass substrate chemically strengthened, includes a primary surface that has a compressive stress layer formed in an uppermost surface layer thereof. The compressive stress layer is configured to enhance strength of the glass substrate due to a compressive stress generated in the compressive stress layer. The compressive layer consists of a layer of a potassium ion concentration equal to or less than 5000 parts per million (ppm). |
