Abstract
A method of manufacturing a glass includes forming a first etch protection layer on a first surface of a glass substrate, and forming a second etch protection layer on a second surface of the glass substrate; removing a part of the first protection layer and a part of the second protection layer by applying a laser pulse penetrating the glass substrate from above the first surface of the glass substrate; forming a cut part in the glass substrate by etching the glass substrate using an etching solution; and removing the first etch protection layer and the second etch protection layer. The second surface is opposite to the first surface.
