<P>PROBLEM TO BE SOLVED: To provide a resin composition for a retardation thin film for forming a retardation thin film for a liquid crystal display device, the thin film having high transparency and high birefringence by applying the composition on a substrate without requiring an alignment or stretching process, and to provide a color filter substrate having a retardation thin film, and a liquid crystal display device having a wide viewing angle and a high contrast. <P>SOLUTION: The resin composition for a retardation thin film for forming a retardation thin film that is used in a liquid crystal display device and that has an optically negative uniaxial anisotropy, an optical axis approximately perpendicular to the thin film plane, and a birefringence Δn in the thickness direction of 0.01 to 0.3. The resin composition contains a polyimide precursor produced by the reaction of tetracarboxylic acid dianhydride with diamine, and an organic solvent, wherein either the tetracarboxylic acid dianhydride or the diamine is an alicyclic compound. <P>COPYRIGHT: (C)2008,JPO&INPIT |
