The present invention discloses an engaged type liquid crystal module. By engaging a first groove disposed in the middle of an outer surface of a backlight module with a first flange of a front frame structure, it can assemble a liquid crystal module, and can save a volume occupied by screw members. The engaged type liquid crystal module according to the present invention can simplify the frame design of the liquid crystal module, and match with a corresponding outer housing of display device to process an assembly operation without screw members, so that it is further advantageous for a development trend that liquid crystal display is designed toward narrow frame.
