Abstract:
1. A green color filter having a green filter layer comprising: a. a first pigment comprising a bridged aluminum phthalocyanine having its maximum absorption at a wavelength from 600 to 700 nm wherein at least 90 volume percent of the first pigment particles have a particle size less than 300 nm; b. a second pigment having its maximum absorption at a wavelength from 400 to 500 nm wherein at least 90 volume percent of the second pigment particles have a particle size less than 300 nm; and c. the green filter layer has a transmittance of 60% or more at a wavelength of 520 nm, of no more than 10% at a wavelength of 590 nm, of no more than 10% at a wavelength of 480 nm, and of no more than 1% at wavelengths from 593 nm to 700 nm.
