Glass substrate and a manufacturing method thereof |
摘要 |
A method for manufacturing a glass substrate by a fusion process includes flowing fused glass into a fusion pipe, and gradually cooling and solidifying the fused glass by allowing the glass to flow downward from the fusion pipe. An asperity is formed on a surface of the glass substrate by fastening and pressing the glass toward a direction of thickness of the glass with a pair of transfer rollers while the glass is flowing down from the fusion pipe.
