(57) Abstract: A liquid crystal composition and a liquid crystal display device capable of high contrast ratio and high-speed response are obtained. A R 1 - (A 1) m -Cy-CF = CF-P a compound represented by the h- (A 2) n -R 2 , R 3 -Ph A compound represented by -CF = CF-Ph-F is included. Ph Is a 1,4-phenylene group, Cy is a trans-1,4-cyclohexylene group, A 1 and A 2 are Ph or Cy, m and n are 0 or 1, and R 1 and R 2 have 1 to 1 carbon atoms. 10 alkyl groups and the like. |
