ABSTRACT:
An electronic display containing a light source and a color filter set, the color filter set comprising: a green color filter having a green filter layer comprising a first pigment 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, and 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 wherein the green filter layer has a transmittance of 60% or more at a wavelength of 520 nm and of no more than 10% at a wavelength of 480 nm and of no more than 10% at a wavelength of 590 nm; a blue color filter having a blue filter layer; a red color filter having a red filter layer; and wherein the color gamut defined by the electronic display has a % NTSCx,y ratio greater than 88%.
