Abstract: PURPOSE: A surface processing method of anti-glare glass is provided to reduce deviation of haze, R Max(maximum roughness) and Ra(average roughness). CONSTITUTION: A surface processing method of anti-glare glass comprises the following steps: manufacturing anti-glare coating agent; manufacturing an etching solution; checking the status of the medicinal fluid and anti-reflective coating liquid and preparing the drive of a surface processing system after filling the returned pure water into a rinse solution storage; pre-processing the glass; loading the pre-processed glass onto the glass surface processing system; coating on one side or both sides of the glass with the anti-reflective coating liquid; primary coating the coated glass with pure water; etching the coated glass surface with etching medicinal fluid and controlling the haze of the surface; secondary washing the etched glass with pure water; unloading the glass; and post processing the unloaded glass.
