Abstract

A method of producing conductor tracks applied to a support, particularly conductor tracks applied on an electrode support of a liquid-crystal display, in which a mask having cutouts corresponding to the conductor tracks is placed on the support and a conductive layer of electrically conductive material is applied corresponding to the cutouts to the support by, for instance, vapor deposition or sputtering. The cutouts are so interrupted at given points by support webs that the mask is imparted a mechanically stable shape in its plane, and that interruptions in the conductor paths are caused by the support webs. This occurs upon the application of the conductor layer of electrically conductive material, partially forming the conductor tracks on the support with interruptions in the conductor tracks masked by the support webs in a first operation by applying the conductive layer of electrically conductive material through the openings of the mask onto the support.
