— Response times and switching voltages of positive‐ and negative‐type nematic liquid‐crystal mixtures are improved by the addition of small amounts of diaryl‐ether derivatives. The effect of such doping is directly seen as a reduction in the rotational viscosities of the mixtures. Despite their non‐planar nature, the dopant molecules do not cause any detrimental changes to the black levels and the contrast ratios of the displays filled with the doped LC mixtures.
