An object of the present invention is to provide a polymerizable liquid crystal compound that does not contain a functional group that is difficult to synthesize, and does not require a complicated process such as light irradiation in an inert gas atmosphere. Provides cholesteric alignment liquid crystal films with excellent mechanical strength. An oxetane compound (A) having an optically active site represented by the following general formula (1), a side-chain liquid crystalline polymer substance (B) having an oxetanyl group, a photocation generator and / or a heat. A polymerizable liquid crystal composition comprising a cation generator (C) and having a weight ratio of (A) :( B) of 0.01: 99.9 to 60:40. Z 1- (CH 2 ) n -L 1 -P 1 -L 2 -C 1 -L 2 -P 1 -L 1- (CH 2 ) n -Z 1 (1) (in formula (1), Z 1 Represents a specific oxetanyl group, L 1 and L 2 each represent a single bond, —O—, —O—CO—, or —CO—O—, and P 1 represents a phenylene group or a substituted phenylene group. Or a biphenylene group, C 1 represents an optically active site, and n represents an integer of 0 to 8.) [Selection figure] None |
