Abstract:
1. A method of manufacturing an antireflective glass, the method comprising: cleaning a surface of a glass; forming a porous structure of nanoscale pores on the cleaned surface of the glass in a thickness direction of the glass by immersing the glass in an alkali solution etchant at a temperature of less than 100° C., etching the cleaned surface of the glass with the alkali solution etchant for 4 hours or less than 4 hours, the etchant being a substitute for hydrofluoric acid (HF) or fluoride such that HF or fluoride is not used as the etchant, wherein the porous structure is formed only by cleaning the surface of the glass and etching the glass with the alkali solution etchant, the etching not requiring any other additional processes, and wherein the porous structure is formed on the cleaned surface of the glass without forming a separate coating layer on the surface of the glass.
