Color filter array having a blue filter layer

摘要

A color filter array having a blue filter layer on a substrate wherein the blue filter layer comprises triallylmethane dye showing its absorption maximum at a wavelength within the range of from 550 to 650 nm; and has a transmittance at a wavelength of 450 nm of 70% or more and that at 650 nm of 5% or less is provided; and the color filter array shows excellent spectroscopic characteristics with respect to blue light and has a blue filter layer excellent in light fastness.
