A liquid crystal composition which prevents production of an alignment defect of a liquid crystal compound and also has excellent storage stability during dissolution in a solvent is provided. The liquid crystal composition is suitable for constituting a retardation film capable of favorable circular polarization conversion. The liquid crystal composition includes a polymerizable liquid crystal compound having 3 or more ring structures in the main chain, and aluminum. A content of the aluminum is 1 ppm or more and 170 ppm or less relative to the polymerizable liquid crystal compound.
本发明提供了一种液晶组合物,它能防止液晶化合物产生排列缺陷,而且在溶解于溶剂时具有极佳的储存稳定性。该液晶组合物适用于构成能够实现良好圆偏振转换的延缓膜。液晶组合物包括主链中具有 3 个或更多环状结构的可聚合液晶化合物和铝。相对于可聚合液晶化合物,铝的含量为 1 ppm 或以上,170 ppm 或以下。
