Abstract:
1. A polymerizable liquid crystal composition containing a polymerizable compound having a mesogen structure comprising the following condensed benzene ring group (A) and the following 6-membered cyclic group (B) bonded to at least one bond in the group (A) directly or via a connecting group —OCO— or —COO—, and a monovalent terminal group bonded to each of both terminals of the mesogen structure, at least one of the terminal groups being a monovalent organic group having a polymerizable moiety, where the condensed benzene ring group (A) is a naphthalenediyl group having bonds at 1-position and at 4- or 5-position, or an anthracenediyl group having bonds at 1- or 9-position and at 4-, 5- or 10-position; and the 6-membered cyclic group (B) is a 1,4-phenylene group, a trans-1,4-cyclohexylene group or a bivalent group having at least two groups selected from these groups bonded directly or via a connecting group, wherein the polymerizable compound is represented by the following formula (1): where R 1 , R 2 , n, J 1 , J 2 , J 3 , E 1 , W 1 and M are as follows: R R n: 0 or 1, J J E W M: a group selected from groups represented by the following formulae (a) to (f):
