Document Type and Number:
WIPO Patent Application WO/2022/080003
Kind Code:
A1
Abstract:
The present invention relates to a color filter that comprises a light source and at least a green pixel part, and converts the color of light from the light source, wherein the light of the light source has a peak wavelength of 500-560 nm within 480-580 nm, intensity (I480) at 480 nm with respect to intensity (I532) at 532 nm is 1.1 or less, intensity (I480) at 480 nm with respect to intensity (I550) at 550 nm is 0.9 or less, and in the CIE XYZ color system at the time of color measurement using the light source, 0.140 ≤ chromaticity x ≤ 0.200, 0.600 ≤ chromaticity y ≤ 0.780 can be displayed, green pixels in the green pixel part contain at least a cyan color material and a yellow color material, and the peak wavelengths of the green pixels are within a range of 500-520 nm.
