Abstract

Provided are liquid crystal compounds and mixtures incorporating the same. The liquid crystal compounds of the invention generally comprise a cyclopentane group and at least two other rings. In one embodiment, the liquid crystal compounds of the invention comprise a cyclopentane group and at least two other rings, one of which is a fused ring system. A formula (I) is shown in the description.

Description

[0001] Cross-references to related applications [0002] This application claims priority to US Provisional Application Serial No. 61 / 027,230, filed February 8, 2008, which is incorporated herein by reference to the extent not inconsistent with the disclosure herein. Background technique [0003] Liquid crystal displays use mixtures of liquid crystals with desirable material properties such as operating temperature range, thermal stability, light stability, response time and contrast. The performance of the mixture and equipment depends on the composition of the mixture. [0004] Demands for liquid crystal displays having high performance have increased. In particular, there is a need for liquid crystal mixtures with low threshold voltages, especially for display applications. The threshold voltage is the amount of voltage required to be applied across a pixel to produce a response. Processing pixels with lower voltages simplifies the electronics used, potentially reducing ...
