The one or more absorbing dyes may be a soluble, blue light, green light, or red light absorbing dye included in blue, green, or red subpixels of the color filter. A blue light absorbing dye may reduce transmission in a wavelength range of 410-430 nm, a green light absorbing dye may reduce transmission in a wavelength range of 490-570 nm, and a red light absorbing dye may reduce transmission of wavelengths less than 620 nm.
