GLASS SUBSTRATE, METHOD FOR PRODUCING GLASS SUBSTRATE AND BLACK MATRIX SUBSTRATE

摘要

A glass substrate which is formed of silicate glass containing aluminum and which is configured so that the value obtained by subtracting the ratio of the atomic concentration of aluminum to the atomic concentration of silicon in the surface of the glass substrate as measured by X-ray photoelectron spectroscopy from the ratio of the atomic concentration of aluminum to the atomic concentration of silicon in the inside of the glass substrate as measured by X-ray photoelectron spectroscopy is 0.25 or less.
