Abstract

An LCD display element is provided that achieves a uniform LCD display panel by arranging individual LCD display elements side-by-side. The margin areas outside of the viewing field in the vicinity of the left and the right lateral edges of the LCD display element are configured to be equally narrow. The narrow width of the margin areas is achievable because row leads do not contact the row electrodes at one of their ends, but rather are routed in the spacing areas between individual column electrodes. Moreover, the electrical contact points are located in the spacing areas. In this manner, the wide lateral margin in the area of the contact points of the row electrodes, as in conventional LCD display elements, is avoided. Because the row leads are routed on the interior of the first cover plate, no contact strip is necessary in the area of penetration through the adhesive rim.
