[PROBLEMS] To provide a polymerizable liquid crystal compound which has a large Δn / n, has good coating properties on an alignment film, and is easily aligned. A polymerizable liquid crystal compound having one or more polymerizable reactive groups represented by the following formula and exhibiting nematic liquid crystallinity, wherein Δn / n (n is an average refractive index, Δn = ne-no) , ne: extraordinary light refractive index, no: ordinary light refractive index) is 0.14 or more, and is a polymerizable liquid crystal compound which is coated on an alignment film and aligned. (R 1 to R 12 may be the same or different; H, —CH 3 , —C 2 H 5 or —OCH 3 , R 13 is —H or —CH 3 , X 1 is X 1 : — (CH 2 CH 2 O) a (CH 2 ) b (O) c -(A is an integer of 0 to 3, b is an integer of 0 to 12, c is 0 or 1 When a = 1 to 3, b = 0 and c = 0, and a = 0 At this time, b = 1 to 12 and c = 1. ) And X 2 is -CN Or -F. ) |
