摘要：
A liquid crystal composition which comprises 1 to 15% of a first component (a compound selected from compounds of the formulae I-a and I-b), 8 to 40% of a second component (a compound of the formula II), 10 to 30% of a third component (a compound of the formula III), and 10 to 45% of a fourth component (a compound selected from compounds of the formulae IV-a, IV-b, IV-c and IV-d) ##STR1## wherein each of R.sup.1, R.sup.2, R.sup.8 and R.sup.12 is a C.sub.1 -C.sub.10 alkyl group, R.sup.3 is a C.sub.1 -C.sub.10 alkyl group or a C.sub.2 -C.sub.10 alkenyl group, each of R.sup.4, R.sup.7 and R.sup.11 is a C.sub.1 -C.sub.10 alkyl group or alkoxy group, each of R.sup.5 and R.sup.9 is a C.sub.2 -C.sub.10 alkenyl group or alkenyloxy group, each of R.sup.6 and R.sup.10 is a C.sub.2 -C.sub.10 alkenyl group, and R.sup.13 is a C.sub.2 -C.sub.10 alkoxyalkyl group.
