The invention provides a liquid crystal module with a waterproof function. The liquid crystal module comprises a front frame, a rubber frame, a colored filter substrate, an array substrate and a COF assembly. The first side of the rubber frame is parallel to the first side of the front frame, and the second side of the rubber frame is parallel to the second side of the front frame. The array substrate is arranged between the first side of the rubber frame and the colored filter substrate, and a control circuit is further arranged on the upper surface of the array substrate. One end of the COF assembly is coupled to the control circuit, the other end of the COF assembly is coupled to a printed circuit board, and a drive chip is packaged on the surface of the COF assembly. A first guide board is arranged on the second side of the rubber frame, a second guide board is arranged on the second side of the front frame, and cleaning liquid is guided out of the module through the first guide board and the second guide board. Compared with the prior art, the guide boards abut against the inner side and the outer side of the COF assembly to change the curvature of the liquid crystal module, and therefore the cleaning liquid is effectively guided to flow out of the module, and the situation that due to the fact that the cleaning liquid is left on the surface of the COF assembly, a metal wire is corroded is avoided.
