The invention relates to the technical field of technical display, and particularly relates to a liquid crystal display panel, a liquid crystal display device and a manufacturing method of the liquidcrystal display panel. The liquid crystal display panel comprises an array substrate, a color film substrate and a liquid crystal layer arranged between the array substrate and the color film substrate; a surface of the array substrate, facing towards the color film substrate, is provided with an isolating cushion object raised towards the color film substrate; a docking groove which is in one-to-one correspondence with the isolating cushion object and is opening towards the array substrate is formed on a surface, facing towards the array substrate, of a non-display area of the color film substrate; and in each pair of mutually corresponding docking groove and isolating cushion object, projection of the docking groove on the array substrate covers projection of the isolating cushion objecton the array substrate. A top part of the isolating cushion object on the array substrate of the liquid crystal display panel falls in the groove, the isolating cushion object is limited by the groove, thus, the top of the isolating cushion object cannot scratch a guide film of a display area of the color film substrate, a problem of uneven display brightness caused by the isolating cushion object is eliminated, and product yield is improved effectively.
