Method of manufacturing a glass substrate for displays and a glass substrate for displays manufactured by same

摘要

A method of manufacturing a glass substrate for displays is provided, which allows efficient and inexpensive removal of at least a reducing heterogeneous layer formed on the top surface of the glass substrate, and a glass substrate for displays manufactured by the same method. A glass substrate is prepared by the float method. The reducing heterogeneous layer formed on the top surface of the glass substrate is removed by etching using an etchant which is mainly composed of hydrofluoric acid.
