摘要：
A mesomorphic compound represented by the following formula [I]:
wherein R 1 and R 2 independently denote an alkyl group having 1-16 carbon atoms capable of having a substituent; Xi, X 2 , X 3 and X 4 independently denote a single bond, -0-,
A 1 , A 2 and A 3 independently denote
; X 5 and X 6 independently denote hydrogen atom, fluorine, chlorine, bromine, CH 3 , CN or CF 3 ; n 1 and n 2 are 0 or 1, with provisos that (1) X 2 cannot be a single bond when n 1 is 0, (2) X 3 cannot be a single bond when N 2 is 1 and (3) at least one of X 2 and X 3 denotes
when both n 1 and n 2 is 0 and A 2 denote
