MANUFACTURING METHOD FOR GLASS SUBSTRATE WITH THIN FILM

摘要

The invention provides a manufacturing method for a glass substrate with a thin film, which allows easy manufacturing of a less warped glass substrate with a thin film. The method performs: a deformation step of plastically deforming a glass substrate 10 to give a principal surface 10a thereof a curved shape so that the principal surface 10a of the glass substrate 10 is flattened in the final state after the formation of the thin film; and a thin film formation step of forming a thin film 11 on the principal surface 10a of the plastically deformed glass substrate 10.
