RESIN COMPOSITION FOR RETARDATION THIN FILM, COLOR FILTER SUBSTRATE FOR LIQUID CRYSTAL DISPLAY DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD FOR PRODUCTION OF COLOR FILTER SUBSTRATE FOR LIQUID CRYSTAL DISPLAY DEVICE HAVING RETARDATION THIN FILM ATTACHED THERETO

摘要

ABSTRACTA resin composition for forming a retarder is disclosed with which orientation and stretching steps are not necessary, and a retarder having a high transparency and high birefringence can be formed by coating the composition on a substrate. Thecomposition comprises a polyimide precursor and an organic solvent, which polyimide precursor is obtained by reacting at least one tetracarboxylic di anhydride and at least one diamine. At least one of the at least one tetracarboxylic dianhydride and the at least one diamine is an alicyclic compound. This composition is used for forming a retarder which is used for liquid crystal displays, which has an opticallynegative uniaxial anisotropy, whose optical axis is substantially vertical to the film plane of the retarder, and which has a birefringence An in the direction of thickness of 0.01 to 03.
