发明名称 Red colored film, red colored composition, color filter and liquid crystal display device
摘要 A red-colored film in which when an elliptically polarized light is incident on the film in a direction 45° aslant from a normal line direction with respect to a surface of the film, a light transmitted through the film has an average amplitude transmittance ratio (av. tan Psi) in a wavelength region of 575 to 635 nm, which satisfies the following equation (1): <?in-line-formulae description="In-line Formulae" end="lead"?>0.960<av. tan Psi<1.040 (1). <?in-line-formulae description="In-line Formulae" end="tail"?> A red-colored composition contains a red pigment A having a BET specific surface area in the range from 90 to 140 m<SUP>2</SUP>/g, a red pigment B having a BET specific surface area in the range from 70 to 85 m<SUP>2</SUP>/g, and a pigment carrier formed of a transparent resin, a precursor of the transparent resin or a mixture of the tarns parent resin and precursor thereof. A color filter has the red-colored film as a red color filter segment. The liquid crystal display device includes the color filter.
