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.
Polyfunctional N-cyanoimides and their precursors and derivatives are disclosed along with methods for their preparation and interconversion. Also disclosed are curable compositions comprising the N-cyanoimides or poly(amide-cyanoamides) and reactive diluents as well as novel dianhydrides, polyimides, and poly(amide-cyanoamides) and methods for making them.
