METHOD FOR MANUFACTURING GLASS SUBSTRATE, AND GLASS SUBSTRATE

A method for producing a glass substrate that has a desired shape and is obtained from a glass plate, the method includes: emitting a first laser beam to the glass plate to form a scribe line over an entire thickness of the glass plate, the scribe line defining a contour line of the glass substrate...

description A method for producing a glass substrate that has a desired shape and is obtained from a glass plate, the method includes: emitting a first laser beam to the glass plate to form a scribe line over an entire thickness of the glass plate, the scribe line defining a contour line of the glass substrate having the desired shape; and performing a fusion-cutting at a position away from the scribe line on a side opposite to the desired shape and removing an unnecessary region of the glass plate along the scribe line to obtain the glass substrate having the desired shape along the contour line.
