Color filter and liquid crystal display

摘要

Disclosed herein is a color filter, which includes a substrate and a green color resist. The green color resist is disposed on the substrate. The green color resist has a function A(λ) defined by a product of the transmittance spectrum of the green color resist and the CIE color matching function z(λ). The function A(λ) has a maximum of less than 0.28, and the function A(λ) satisfies the following formula (II):
∫380780A(λ)dλ>10.26  formula (II).

1. A color filter, comprising:
a substrate; and a green color resist disposed on a surface of the substrate, wherein the green color resist has a transmittance spectrum T(λ) which is a function of the wavelength λ of light passing through the green color resist, and a function A(λ) defined by a product of the transmittance spectrum T(λ) and a CIE color matching function z(λ) the function A(λ) being represented by the following formula (I):
A(λ)=T(λ)× z(λ)  formula (I), wherein the function A(λ) has a maximum of less than 0.28 when the wavelength λ is in the range from 380 nm to 780 nm, and the function A(λ) satisfies the requirements of the following formula (II):
∫380780A(λ)dλ>10.26  formula (II); wherein the transmittance spectrum T(λ) has a maximum of greater than 0.9, and the transmittance spectrum T(λ) produces a chromaticity x of 0.28 to 0.327 and a chromaticity y of 0.6 to 0.62 in the CIE 1931 chromaticity diagram, wherein a CIE standard illuminant C is used as a theoretical light source.
