ABSTRACT:
A liquid crystal cell having a pair of carrier plates, which are spaced apart from one another by a frame with each of the plates on an inner surface containing electrically conductive coatings, characterized by the electrical conductive coatings on one of the two carrier plates forming an electrode and being connected to a terminal electrode arranged on the inner surface of the other character plate by a conductor bridge, which is located on the outside of the frame and comprises a metallization which serves to contact the two end surfaces of the two electrodes which end surfaces extend to the plane of the edges of their respective carrier plate. The process for forming the liquid crystal cell includes forming a plurality of the carrier plates on a single member and subsequently subdividing the single member into the individual carrier plates with the step of subdividing ensuring that the edge of the electrodes lies in the plane of the edge of the carrier plate. In addition, the process includes providing an insulating layer with the edge of the electrodes being masked and also portions adjacent the edge of the electrodes being masked from the material forming the insulating layer.
