Abstract: An optical film structure includes film sets, each of which includes a first film and a second film that are stacked up in an axis. For each of the film sets, the first film has a higher refractive index than the second film, and a thickness ratio of the first film to the second film is larger than 0 and is less than or equal to 0.28. Therefore, the optical film structure is applicable to a variety of devices or components whose filter properties change with different incident angles of light.

Abstract: A color filter and a manufacturing method thereof are disclosed. The color filter includes a plurality of first black matrixes and a plurality of second black matrixes disposed on a substrate, and each of the second black matrixes is positioned between adjacent two of the first black matrixes. The first black matrixes define a plurality of sub-pixels, and the second black matrixes are located in the sub-pixels. A plurality of color layers are positioned in the sub-pixels, and portions of the color layers are positioned on the second black matrixes to form a plurality of protrusions.
