Abstract

A liquid crystal display is provided with several drive segments, between which at least one intermediate surface without drive segments is situated. Such liquid crystal displays are used, in particular, for displaying information contents of low information density, for example, as numerical display elements. This realizes, among other things, a simple and cost-efficient improvement of the electrostatic properties and the legibility, namely also under unfavorable light conditions. For this purpose, the intermediate surface is largely provided with at least one conductive auxiliary layer and a high-frequency connection between the auxiliary layer and a shielding potential is produced.
