Patent ID: 7763672

Claim:
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 Ψ) in a wavelength region of 575 to 635 nm, which satisfies the following equation (1): 0.960< av. tan Ψ<1.040 (1), the red-colored film being formed from a red colored composition comprising a red pigment A which is a C.I. Pigment Red 254 having a BET specific surface area in the range from 90 to 140 m 2 /g, a red pigment B which is a C.I. Pigment Red 254 having a BET specific surface area in the range from 70 to 85 m 2 /g, and a pigment carrier comprising a transparent resin, a precursor of the transparent resin or a mixture of the transparent resin and precursor thereof, wherein the red pigment B is contained in an amount of 10 to 60 parts by weight relative to 100 parts by weight of the red pigment A.
