摘要：
The present invention relates to trans-olefin compounds represented by the general formula (1) useful as an ingredient of liquid crystal composition, trans-olefin compounds useful as intermediate of pesticides, medical drugs, liquid crystal materials and the like, a process for producing those trans-olefin compounds, a liquid crystal composition containing the trans-olefin compound as an active ingredient, and a liquid crystal element using the liquid crystal composition. ##STR1## (In the general formula (1), R.sup.1, A.sup.1, A.sup.2, A.sup.3, Z and R.sup.2 are same as defined in the specification. Also, m, p, q, n, r, s and t are each an integer as defined in the specification.)
