Abstract:
1. A polymerizable liquid crystal compound represented by the formula (1): wherein R wherein R b1 and R b2 independently represent hydrogen, halogen, alkyl having from 1 to 5 carbon atoms or halogenated alkyl having from 1 to 5 carbon atoms, and wherein at least one R a represents a polymerizable group represented by one of the formulae (p-1) to (p-6); A independently represents 1,4-cyclohexylene, 1,4-cyclohexenylene, 1,4-phenylene, naphthalen-2,6-diyl, tetrahydronaphthalen-2,6-diyl, fluoren-2,7-diyl or bicycle [2.2.2]octan-1,4-diyl; in which one or two —CH Z independently represents a single bond or alkylene having from 1 to 20 carbon atoms; in which in the alkylene, arbitrary —CH Y independently represents a single bond or alkylene having from 1 to 20 carbon atoms; in which in the alkylene, arbitrary —CH m and n independently represent an integer of from 0 to 5.
