Abstract
A cholesteric polymerizable liquid crystal composition excellent in UV curing property and alignment property is provided. The polymerizable liquid crystal composition contains at least one liquid crystal compound selected from compounds represented by Formula (1-1) and Formula (1-2), at least one liquid crystal compound selected from compounds represented by Formula (2), and 5 to 15% by weight of at least one optically active compound selected from compounds represented by Formula (4) and may contain at least one liquid crystal compound selected from compounds represented by Formula (3). The meanings of the symbols in the Formulae are described in the specification.
