Disclosed is a liquid crystal element with an improved orientation layer and a coating composition for forming such an orientation layer. The orientation layer consists essentially of a polymer with a Mark-Houwink coefficient of not less than 0.85, the Mark-Houwink coefficient being represented by the formula [I]: n [η] = K·M α [I] nwherein [η] represents intrinsic viscosity of the polymer determined by solution viscosity measuring method, K represents a constant, M represents molecular weight of the polymer, and α represents the Mark-Houwink coefficient. The coating composition comprises a polyfumaric acid ester represented by the formula [II]:n wherein R¹ and R², the same or different, represent straight or branched alkyl group, cycloalkyl group, haloalkyl group, silalkyl group or siloxanylalkyl group; and a halogen-containing organic solvent. |
