[0071] (Example)
[0072] The polymerizable liquid crystal composition (A) of the composition shown below was prepared.
[0073] [化9]
[0074]
[0075] When the polymerizable liquid crystal composition (A) is heated to the isotropic liquid phase at one time and then cooled, the phase changes to the nematic phase at 70°C and the smectic A phase at 35°C. The smectic A phase is also maintained at room temperature. To this composition (A), 3% of the photopolymerization initiator IRGACURE907 (manufactured by Ciba Chemicals) and 0.01% of polypropylene with a mass average molecular weight of 1650 as a horizontal orientation additive were added to prepare a composition (A-1) . Furthermore, the composition (A-1) was dissolved in propylene glycol monomethyl ether acetate so that the concentration became 30%, to prepare a coating composition (A-2).
[0076] Next, a TAC film (thickness 50 μm) with a width of 15 cm and a length of 15 cm was prepared, and rubbing treatment was pe...
