Abstract:
1. A polymerizable liquid crystal compound represented by formula (1): wherein at least one of R and R a that is not a polymerizable group is chlorine, fluorine, cyano, alkyl having 1 to 10 carbons, alkoxy having 1 to 10 carbons, —CF 3 or —OCF 3 ; A is independently 1,4-cyclohexylene, 1,4-cyclohexenylene, 1,3-dioxane-2,5-diyl, pyridine-2,6-diyl, pyridazine-3,6-diyl, pyrimidine-2,6-diyl, naphthalene-2,6-diyl, tetrahydronaphthalene-2,6-diyl, fluorene-2,7-diyl, bicyclo[2.2.2]octane-1,4-diyl, or 1,4-phenylene in which arbitrary hydrogen may be replaced by halogen, cyano, —NO B is phenyl in which arbitrary hydrogen may be replaced by halogen, cyano, —NO Z is independently a single bond or alkylene having 1 to 20 carbons, and in the alkylene, arbitrary —CH Y is independently a single bond or alkylene having 1 to 20 carbons, and in the alkylene, arbitrary —CH m and n are each independently an integer from 0 to 5; and R
