PROBLEM TO BE SOLVED: To provide a method for inexpensively producing a glass substrate for a display cover glass, the glass substrate not only having excellent strength and antibacterial properties but having high transparency and transmittance for visible light, which is suitable as a cover glass of a display device. SOLUTION: In the method for producing a glass substrate for a display cover glass, which includes a surface compressive stress layer and an antibacterial substance-containing layer on the surface of the glass substrate, shows 0.95 or more of a ratio (T1/T2) of the transmittance T1 at a wavelength of 428 nm to the transmittance T2 at a wavelength of 650 nm of the glass substrate, and shows a transmittance of 86% or more at a wavelength of 428 nm when the plate thickness of the glass substrate is 0.1 to 3.0 mm. The method includes steps of: subjecting a glass substrate simultaneously to a chemical reinforcing treatment and an antibacterial treatment in a molten salt containing at least 75 to 99.9999 mass% of KNO<SB>3</SB>and 0.0001 to less than 0.1 mass% of AgNO<SB>3</SB>; and cleaning the glass substrate subjected to the chemical reinforcement and antibacterial treatment.
