A color filter and a manufacturing method thereof, as well as a liquid crystal display panel are disclosed. The color filter comprises a color resistance layer, a flat layer, and a first black matrix, wherein the flat layer is coated on the color resistance layer, and the first black matrix is arranged in the flat layer. According to the present disclosure, the critical angle of the color shift phenomenon of the color filter can be increased effectively, and thus the color shift phenomenon of the liquid crystal display panel under wide viewing angles can be alleviated.
