Green color filter element

Abstract

A green color filter having a green filter layer comprising a bridged aluminum phthalocyanine pigment and a second pigment having its maximum absorption at a wavelength from 400 to 500 nm.

1 - 26 . (canceled) 
     
     
         27 . A method of forming a green color filter having a green filter layer comprising the steps of:
 a) providing a pigment mixture containing a first pigment, a carrier for the pigment, and a dispersant;   b) mixing the pigment mixture with rigid milling media having an average particle size less than 100 micrometers;   c) introducing the mixture of step b) into a high-speed mill;   d) milling the mixture until a pigment dispersion is obtained wherein at least 90 volume percent of the pigment particles have a particle size less than 100 nm;   e) separating the milling media from the dispersion milled in step d);   f) repeating steps a) to e) for a second pigment;   g) combining the dispersions of first and second pigments; and   h) coating the resulting dispersion onto a substrate to form a green filter layer.   
     
     
         28 . The method of  claim 27  wherein the carrier for the pigment is water or an aqueous solvent mixture. 
     
     
         29 . The method of  claim 27  wherein the carrier for the pigment is a non-aqueous solvent.
