Abstract
A method of manufacturing a plurality of glass members comprises bringing a first main surface of a glass substrate in contact with a first working surface of a first mold substrate, the first working surface being provided with a plurality of first protruding portions, and bringing a second main surface of the glass substrate in contact with a second working surface of a second mold substrate, the second working surface being provided with a plurality of second protruding portions. The method further comprises controlling a temperature of the glass substrate to a temperature above a glass-transition temperature to form the plurality of glass members, removing the first and the second mold substrates from the glass substrate, and separating adjacent ones of the plurality of glass members.
