Abstract: The present invention provides a compound represented by the general formula (I), and a polymerizable composition containing the compound. When the polymerizable composition containing the compound represented by the formula (I) is used to form a filmy product, the resulting filmy product exhibits less change over time in phase difference and reverse wavelength dispersion and when the filmy polymer is irradiated with UV light, peeling from a substrate is unlikely to be caused. Further, the invention provides a polymer obtained through polymerization of the polymerizable composition and an optically anisotropic body obtained using the polymer.

Abstract: The present invention provides a compound represented by General Formula (I). The compound according to the present invention prevents the liquid crystal composition from being deteriorated due to light, has high compatibility with the liquid crystal composition, and does not impair the storage stability of the liquid crystal composition, thus the compound is useful as a constituent member of a liquid crystal composition. Since the liquid crystal composition and the liquid crystal display element containing the compound of the present invention exhibit UV resistance and have a high VHR, it is possible to obtain a liquid crystal display element with excellent display quality in which display defects such as burn-in and display unevenness do not occur or are suppressed.
