Patent ID: 7070711

Claim:
A polymerizable liquid crystalline composition comprising (A) an oxetane compound having an optically active portion represented by formula (1) below, (B) a side chain liquid crystalline polymeric substance having an oxetanyl group, and (C) a photo cation generator and/or a thermal cation generator, the weight ratio of Compound (A) to Compound (B) being within the range of 0.01:99.99 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) wherein Z 1 is a group represented by formula (2), (3) or (4) below, L 1 and L 2 are each independently a single bond, —O—, —O—CO—, or —CO—O—, P 1 is a group represented by formula (5) or (6) below, C 1 is an optically active site, and n is an integer of 0 to 8; wherein X is selected from the group consisting of hydrogen, methyl, and halogen.
