ABSTRACT:
The present invention provides a glass sheet formed on molten tin, that exhibits a high transmittance that is originally inherent to its composition. In this glass sheet, the difference between a visible light reflectance of a surface formed in contact with the molten tin and a visible light reflectance of a surface on the opposite side thereof is not greater than 0.25%. And when the glass sheet's thickness is 4 mm, a light transmittance at 540 nm wavelength is at least 91.5%, and a light transmittance at 450 nm wavelength is at least 91.0%, and after irradiating UV light for 6 hours as specified in the radiation-proofing test according to JIS R3212, a light transmittance at 540 nm wavelength is at least 91.0% and a light transmittance at 450 nm wavelength is at least 90.5%.
