Abstract: A backlight module and a display device are provided. The backlight module includes a light-emitting substrate and a reflective film layer disposed on a light-exiting surface of the light-emitting substrate. The light-emitting substrate includes a base substrate and light-emitting elements and light-scattering members disposed on one same surface of the base substrate. The reflective film layer includes a plurality of light-exiting holes for light passing through. A part of the light emitted by the light-emitting elements is reflected to the light-scattering members by the reflective film layer and is scattered by the light-scattering members. Therefore, light intensity of regions between the light-emitting elements is enhanced.
