  • OPTICALLY ANISOTROPIC COMPOUND AND RESIN COMPOSITION COMPRISING THE SAME
    Publication number: 20100137484
    Abstract: Disclosed is a compound having high optical anisotropy and high compatibility with a polymer resin, which is represented by Formula 1 and necessarily has at least one meta substituent. Also, a resin composition including the compound and a polymer resin, and an optical member including the resin composition are disclosed. Since the compound represented by Formula 1 is an anisotropic compound having high compatibility with a polymer resin and high optical anisotropy, in the case of an optical member obtained by using a polymer resin composition including the compound represented by Formula 1, there is no phase separation, and it is possible to achieve a required optical characteristic with only a small amount thereof.
