Claim Text:
1. A cholesteric liquid-crystal mixture containing a compound represented by the following general formula (Ia), a compound represented by the following general formula (Ib), a fluorine-containing horizontal alignment agent and a polymerization initiator: wherein, in the general formulae (Ia) and (Ib), Z 1 , Z 2 and Z 3 each independently represent a polymerizable group; A 1 , A 2 and A 3 each independently represent a spacer having an atom-bonding chain length of from 1 to 30, provided that the spacer represents an alkylene group, or a linking group of multiple alkylene groups bonding to each other via —O— or —CO—; M 1 and M 2 each independently represent (-T 1 -Y 8 ) n -T 2 -; n indicates a natural number; when n is 2 or more, then multiple (-T 1 -Y 8 )'s may be the same or different; T 1 and T 2 each independently represent a saturated or unsaturated hydrocarbon ring, or a saturated or unsaturated hetero ring, provided that the hydrocarbon ring and the hetero ring may have a substituent; Y 1 , Y 2 , Y 3 , Y 4 , Y 5 , Y 7 and Y 8 each independently represent a single bond, —O—, —CO—, —O—CO—, —CO—O— or —O—CO—O—; P represents a hydrogen atom or an alkyl group having from 1 to 15 carbon atoms, and wherein the fluorine-containing horizontal alignment agent is a compound represented by the following general formula (I): wherein L 11 , L 12 , L 13 , L 14 , L 15 and L 16 each independently represent a single bond, —O—, —S—, —CO—, —COO—, —OCO—, —COS—, —SCO—, —NRCO—, or —CONR—; R represents a hydrogen atom or an alkyl group having from 1 to 6 carbon atoms; Sp 11 , Sp 12 , Sp 13 and Sp 14 each independently represent a single bond or an alkylene group having from 1 to 10 carbon atoms; A 11 and A 12 each represent a trivalent or tetravalent aromatic hydrocarbon; Hb 11 represents a perfluoroalkyl group having from 2 to 30 carbon atoms; m11 and n11 each independently indicate from 0 to 3, and m11+n11≧1; T 11 represents a divalent group represented by any of the following or represents a divalent aromatic heterocyclic group: wherein X represents an alkyl group having from 1 to 8 carbon atoms, an alkoxy group, a halogen atom, a cyano group or an ester group; Ya, Yb, Yc and Yd each independently represent a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; and o and p contained in T 11 each independently indicate an integer of 0 or more.
