Abstract
A polymerizable liquid crystal compound represented by Formula (I):Q—Sp—[A—L]—A—Sp—Q  (I) A represents a divalent nitrogen-containing saturated cyclic group (that may have a substituent) formed by removing two hydrogen atoms from piperidine or piperazine, a phenylene group that may have a substituent, or a trans-1,4-cyclohexylene group that may have a substituent; L represents a linking group such as —C(═O)O— or —OC(═O)—; m represents 3 to 12; Spand Sprepresent an alkylene group having 1 to 20 carbon atoms; any one of Qand Qrepresents a polymerizable group; and Formula (I) has a nitrogen-containing saturated cyclic group and a phenylene group that are directly bonded to each other via —C(═O)O—. By using a polymerizable composition including the polymerizable liquid crystal compound, a film such as a retardation film can have low birefringence or a reflection film can have high selectivity in a reflection wavelength range.
