(57) [Summary] [PROBLEMS] To expand the operating temperature range of liquid crystal display characteristics by improving compatibility, improving low-temperature storage, etc., to reduce driving voltage and improve its temperature change, and to compare with a predetermined driving voltage. Achieve or improve fast response. Also, depending on the liquid crystal material having the desired birefringence, MIM or TFT-LCD or ST Various display characteristics of N-LCD are improved, and the display characteristics of PN-CLD and PDLC are improved by a liquid crystal material having a relatively large birefringence. SOLUTION: The liquid crystal composition has a general formula (I-1) to an unsubstituted or substituted naphthalene-2,6-diyl ring. A nematic liquid crystal composition containing the compound (I-3), and a liquid crystal display device using the same. |
