Liquid crystal display panel and manufacturing method thereof

The invention provides a liquid crystal display panel and a manufacturing method thereof, and relates to the technical field of liquid crystal displayers. Manufacturing a color film substrate; manufacturing a liquid crystal box, and assembling and detecting a finished product; a black photosensitive resin layer is coated on two surfaces of a glass substrate, a black grid and a black matrix are formed through exposure and development of an eye mask plate, the black matrix corresponds to a pixel in position and is used for shielding light leakage caused by disorder arrangement of liquid crystal molecules and the like at a pixel junction part, after the black matrix is formed, a red organic photosensitive layer is coated firstly, and then the black grid and the black matrix are formed. The method comprises the following steps of: exposing an eye mask, developing and forming, forming a red filter layer corresponding to a pixel, repeating the procedures, sequentially forming a green filter layer and a blue filter
