The invention relates to the technical field of display, and discloses a display module and a making method thereof. The display module includes a display panel, a backlight module and a flexible circuit board. The flexible circuit board is electrically connected with the display panel, the backlight module includes a light source, and the light source is fixed to the side, facing the display panel, of the flexible circuit board and electrically connected with the flexible circuit. Since the light source is fixed to the side, facing the display panel, of the flexible circuit board, the flexible circuit board is electrically connected with the display panel, and the light source is directly fixed on the main flexible circuit board. Compared with the prior art, the distance from the light-out face of the light source to a display region can be reduced, then the area of the display region is expanded, and the narrow-bezel technical effect is thus achieved; a light-bar flexible circuit board is omitted, the flexible circuit board directly supplies power to the light source, the light-bar welding process is not needed, the structure of the backlight module is thus simplified, and the structure of the whole display module becomes thus simple.
