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.

Substrate made of glass and method for the production thereof

A method for producing a display comprising a carrier substrate made of glass, the display having flexible, bendable and/or elastic properties in a predetermined region of the carrier substrate, includes introducing modifications into the carrier substrate within the region by laser radiation along a closed and/or linear contour and/or points. Within the region, a one flexible, bendable and/or elastic layer is applied. A side of the carrier substrate facing away from the layer is subjected to an etching attack, by which material removal from the carrier substrate takes place along the modifications along the contour and/or at the points of the region until recesses are produced that extend across or over a substantial part of a material thickness of the carrier substrate.
