Abstract
A phase difference film characterized in that said film is obtained by orienting and fixing, on a substrate, a composition containing a polymerizable liquid crystal monomer represented by the following formula (I): wherein, in the formula (I), X represents any one of Br, a halogen atom other than Br, —SMe and —SPh, R1 and R2 represent each independently a hydrogen atom or a methyl group, R3 and R4 represent each independently an alkylene group of a carbon number of 2 to 12, and R5 and R6 represent each independently —O—CO— or —CO—O—.
