Abstract:
The present invention relates to a glass substrate, having a specific matrix composition and including an etched surface having the number of protrusions of 400 or more and 2,000 or less on at least one of main surfaces, in which the number of protrusions is obtained by measuring a region of 285.12 μm×213.77 μm with a laser microscope to obtain XYZ data of a surface shape, and conducting a shape analysis of the XYZ data by using an image processing software SPIP manufactured by Image Metrology.
