A color filter for liquid crystal displays, has a red colored layer wherein a first red pigment where a 40%-transmittance wavelength at a short-wave end of a transmitted spectrum (short-wave 40%-transmittance wavelength) is in a range of 550 to 600 NM and a second red pigment where the short-wave 40%-transmittance wavelength is within 40 NM from the range of the first red pigment are mixed so that transmittance in a wavelength region of 450 to 500 NM is substantially 0%.
