    摘要： 3,4-Dicarboxy-1,2,3,4-tetrahydro-6-t-butyl-1-naphthalene-succinic dianhydride is provided. The tetracarboxylic dianhydride is represented by Formula 1, which is described in the specification. Further provided is a liquid crystal aligning agent comprising a polyimide prepared using the tetracarboxylic dianhydride and a solvent. Further provided is a liquid crystal alignment layer formed using the liquid crystal aligning agent. The liquid crystal alignment layer exhibits excellent electro-optical properties and good processability in terms of printability.
