Abstract
The object of the process is to achieve economical mass production of such arrangements in that case where the spacing of adjacent conductor tracks situated in one plane is large compared to the spacing of conductor tracks situated opposite one another. This is achieved by a non-metallic soldering agent or curable binder (10) being admixed with metal particles (20) whose largest extent corresponds approximately to the spacing of the conductor tracks (5', 6') situated opposite one another. The contact bridges are particularly suitable in the fabrication of liquid-crystal cells. By means of said contact bridges, all the connections of the cell can be arranged on one cell board, which is particularly advantageous for multiplex-driven liquid-crystal cells. The binder (10) with the metal particles (20) at the same time serves as a sealing web of the cell.
