Abstract
Provided are color filters formed of alternately stacked inorganic materials having different refractive indices, a color filter array, a method of manufacturing the color filter array, and an image sensor. A color filter can include a substrate and first and second inorganic films configured to filter light of a specific wavelength corresponding to a predetermined color, wherein the first and second inorganic films can be alternately stacked on the substrate and have different refractive indices from each other. The refractive index difference between the first inorganic film and the second inorganic film is at least 0.8. The color filter can be formed by alternately stacking the first and second inorganic films. The first inorganic film and the second inorganic film can have a refractive index of 1.3 to 6.0 in a visible light region of 400 to 700 nm, and can be formed of a material selected from the group consisting of SiO, SiON, SiN, and Si.
