Abstract
An object of the present invention is to provide a liquid crystal display exhibiting excellent display performance. The object of the present invention is achieved by a colored polymer thin film having an average refractive index of 1.60 to 1.90, and an absolute value of birefringence of 0.01 or less, and a color filter and a liquid crystal display using the colored polymer thin film. The color filter using the colored polymer thin film of the present invention exhibits reduced retardation, and can thus provide a liquid crystal display exhibiting excellent display performance.
