ABSTRACT:
A mixing component for nematic liquid-crystalline substances used in optoelectronic components for the rendition of numbers, symbols and images. The object of the invention is to reduce, in components for nematic liquid crystal substances, the threshold and operating voltages. It has been found, that the addition of one or more 1-oxa-2,6,7-trioxane-1-phospha-bicyclo-derivatives having the general formula ##STR1## wherein ##STR2## with R.sup.1 =C.sub.n H.sub.2n+1 --, C.sub.n H.sub.2n+1 O--, C.sub.n H.sub.2n+1 COO--, C.sub.n H.sub.2n+1 OCOO--, R.sup.2 +C.sub.n H.sub.2n=1 --
with n=an integer from 1 to 10
to nematic liquid crystal substances, considerably reduces the operating voltage.
