<p>The invention relates to a liquid crystal orientation agent and a liquid crystal display element. The liquid crystal orientation agent provides a liquid crystal orientation film which gives full play of the advantages of a transverse-electric-field type liquid crystal display element and lowers the light transmission rate under a dark state when no electric field is generated. Moreover, the liquid crystal orientation film has excellent ghost property. The liquid crystal orientation agent contains at least one polymer selecting from a group containing polyamide acids and polyimides, wherein at least partial of the molecular of the polymer simultaneously has two special structures represented presented by following formulas.</p> |
