GLASS SUBSTRATE HAVING MICROSTRUCTURE AND PRODUCTION METHOD FOR GLASS SUBSTRATE HAVING MICROSTRUCTURE

摘要

This glass substrate (1) having a microstructure has first pores (21) and second pores (22). The first pores (21) have a diameter not more than 1000 µm in a first main surface (11). When that diameter is defined as D, the second pores (22) have a maximum dimension of at least 1.1D in the first main surface (11).
