摘要：
An object of the present invention is to obtain color filters having a high contrast, a high color purity and an improved transmittance for blue color, and a display using the color filters. In the present invention, there is used a colored composition for color filter comprising at least one coloring agent, a base polymer and at least one solvent, said base polymer containing a polyamicacid whose light transmittance decreases by 2% or less in the visible region (wavelength: 400 nm to 800 nm).
