PURPOSE: Nematic liquid crystal composition which keeps the nematic liquid phase over broad temperature range and has an improved optical anisotropy and operating voltage features by containing nonpolar compounds, and thus improved liquid crystal display element by using the composition are provided. CONSTITUTION: A nematic liquid crystal composition which can provide enhanced liquid crystal display element is characteristically containing a nonpolar compound represented as a formula 1 below: wherein A is cyclohexane or benzene ring, and R¬1, R¬2 and R¬3 means independently alkyl or alkoxy having carbon number of 1-12, respectively. Also, R¬1, R¬2 and R¬3 can be characteristically and independently ethyl, propyl, butyl, pentyl or hexyl. |
