Abstract

A substrate made of glass includes an essentially dimensionally stable portion, one or more flexible portions, and one or more recesses on one side or which do not penetrate the substrate, and which is/are disposed in an outer surface of the substrate, so as to reduce a material thickness of the substrate in the flexible portion relative to an adjacent portion. The recess is formed in each case by a plurality of concave depressions that are defined by microstructures, a course of which determines a remaining material thickness of the substrate in the flexible portion. The depressions extend at least in portions into an area having a thickness parallel to the outer surface which on bending the substrate encloses a plane of a neutral axis between an extension zone and a compression zone of the substrate.
