PROBLEM TO BE SOLVED: To provide a liquid crystal composition that satisfies at least one characteristic of characteristics such as a high upper limit temperature of a nematic phase, a low lower limit temperature of a nematic phase, low viscosity, proper optical anisotropy, big dielectric anisotropy to negative, large specific resistance, high stability to ultraviolet, high heat stability, etc., and has appropriate balance in terms of at least two characteristics and an AM (active matrix) element having a short response time, large voltage retention, a large contrast ratio, long service life, etc. SOLUTION: The liquid crystal composition comprises a specific compound having big dielectric anisotropy to negative as a first component, a specific bicyclic compound having low viscosity as a second component and has negative dielectric anisotropy. The liquid crystal liquid crystal display device includes the composition. COPYRIGHT: (C)2011,JPO&INPIT |
