Patent ID: 8054419

Claim:
A color filter, comprising: a transparent substrate; at least a red filter film disposed on the transparent substrate; at least a blue filter film disposed on the transparent substrate, wherein a light with a first wavelength transmits from the blue filter film, the transmittance of the light has a first largest transmittance; at least a green filter film disposed on the transparent substrate, wherein a light with a second wavelength transmits from the green filter film, the transmittance of the light has a second largest transmittance; and at least a white filter film disposed on the transparent substrate, and the white filter film is doped with cyan pigment, wherein a light with third wavelength transmits from the white filter film, the transmittance of the light has a third largest transmittance, and wherein the third wavelength is between the first wavelength and the second wavelength, the third largest transmittance is larger than the first largest transmittance and the second largest transmittance.
