Abstract:
The present description relates to a polymerizable liquid crystal compound, a polymerizable liquid crystal composition including the same, and an optically anisotropic body. The polymerizable liquid crystal compound includes a radical derived from the first liquid crystal molecule including a mesogen group having a non-aromatic ring; a radical derived from the second liquid crystal molecule including a mesogen group that has a structure different from said mesogen group having a non-aromatic ring and includes a ring containing a double bond; and a linker that has a specific structure and links the sp3-hybridized carbon in the non-aromatic ring of the radical derived from the first liquid crystal molecule and the sp2-hybridized carbon in the mesogen group of the radical derived from the second liquid crystal molecule, wherein at least one of the radicals derived from the first and the second liquid crystal molecules may include one or more polymerizable groups which are connected to the mesogen group directly or via spacer groups. Such polymerizable liquid crystal compound makes it possible to exhibit stable reverse wavelength dispersion solely or by being mixed with other liquid crystal materials.
