ABSTRACT:
A liquid crystal display cell including a liquid crystal layer contained between two plane-parallel support plates provided with electrode layers on their mutually inward facing surfaces as well as a border. The support plates are held apart within a predetermined separation range by means of spacers. Those spacers distributed in the border are electrically conductive and serve as contact bridges between through-contact points on the support plates. Rubber-like elastic particles, e.g. from a silicone elastomer, are used as spacers to prevent low pressure bubbles in the liquid crystal layer at temperatures of -30.degree. C. as well as to prevent loss of contact between the through-contact points. The rubber-like elastic particles, between the through-contact points are electrically conductive.
