The invention discloses a color film substrate, a thin film transistor (TFT) array substrate, a manufacturing method thereof and a liquid crystal display panel, relates to the field of liquid crystal display manufacture, and solves the problem that thickness of boxes required by unit display panels of different sizes on a whole display panel is different. The manufacturing method of the color film substrate includes that a public electrode layer is coated on a substrate provided with a black matrix and a color filter, and a half-transparent mask plate or a grey tone mask plate is used for performing picture composition processing on the public electrode layer to obtain a public electrode layer with different thickness of the color film substrate with different size units corresponding to the color film substrate. The color film substrate, the TFT array substrate, the manufacturing method of the color film substrate and the TFT array substrate and the liquid crystal display panel are suitable for manufacturing
