  • POLYMERIZABLE LIQUID CRYSTAL COMPOUND, A LIQUID CRYSTAL COMPOSITION COMPRISING THE COMPOUND, AND AN OPTICALLY ANISOTROPIC BODY
    Publication number: 20150099820
    Abstract: The present invention relates to a polymerizable liquid crystal compound, a liquid crystal composition including the same, and an optically anisotropic body. The polymerizable liquid crystal compound according to the present invention has not only high birefringence but also excellent coating orientation, and thus it is possible to prepare a optically anisotropic body which is thin but superior in optical properties.
    Type: Application
