| titleOfInvention | 3D cover glass and method of manufacturing the same |
| abstract | An object of the present invention is to provide a method for efficiently and high-quality removing defects generated on the surface of a molded 3D cover glass. A method of manufacturing a 3D cover glass having a flat central portion and a curved surface portion forming a three-dimensional curved surface in at least a part of the peripheral portion, the glass material having a shape including the curved surface portion forming a three-dimensional curved surface. A glass forming process for forming, a polishing process for polishing the surface of the glass material obtained after the glass forming process, and a chemical strengthening process for performing a chemical strengthening process on the glass material after the polishing process In the polishing step, the surface hardness of the glass material obtained after the glass forming step is maintained in a state in which a portion corresponding to the central portion of the manufactured 3D cover glass is maintained in a flat state without warping. The manufacturing method of 3D cover glass which polishes more than the depth of the concave fault which appears on the surface of the above-mentioned glass material using 20 [degree]-80 [degree] polishing pad or brush, and polishing slurry .
