Substrate with a liquid crystal polymeric thin film and method for manufacturing the same

摘要

Disclosed herein is a substrate with a liquid crystal polymeric thin film comprising a substrate, an orientation film formed on said substrate and a thermotropic liquid crystal polymeric thin film formed on said orientation film, in which the orientation film comprises a polyimide having a glass transition point of higher than 300 DEG C. obtained by cyclizing a polyamic acid or its derivative coated on said substrate and applying a rubbing treatment.
