摘要： Nematic liquid crystalline substances as additives in mixtures for electro-optical systems for the rendition of numbers, symbols and images. The additives provide new liquid crystalline substances of broad mesophase ranges which improve the chemical stability of the substance mixtures. It has been found that liquid crystalline 5-alkyl-pyridine-2-carboxylic acid esters of the general formula ##STR1## are suitable for utilization in mixtures for electro-optical displays for the rendition of numbers, symbols and images.
