Abstract
Abstract In a device for the electrically conductive connection of a liquid-crystal cell to a circuit board, the liquid-crystal cell and the circuit board are substantially perpendicular to each other and have conductive paths which fit each other, the conductive paths being connected to each other by solder within an angle formed by them. A slot can be provided in an edge region of the circuit board in order to receive an edge region of the liquid-crystal cell.
