Abstract
A display device and color filter substrate thereof are provided. The color filter substrate includes a substrate and a green color filter disposed on the substrate. A concentration of halogen in the green color filter is less than 10 ppm. The green color filter has a transmittance spectrum G(λ), and CMF_Z(λ) is the color matching function defined by International Commission on Illumination (CIE). A peak intensity between 380 nm and 780 nm of G(λ)×CMF_Z(λ) is in a range between 0.33 and 0.4.
