Abstract: A backlight module, a display module, and a display device are provided. The backlight module includes a light-emitting area including a first light-emitting area and a second light-emitting area. The second light-emitting area at least partially surrounds the first light-emitting area. The backlight module also includes a light-emitting structure including a plurality of light-emitting elements distributed in the light-emitting area, and a diffusion plate located on a side of a light exiting surface of the light-emitting structure and at least partially located in the light-emitting area. The backlight module also includes a reflection structure located on a surface of the diffusion plate facing the light-emitting structure. The reflection structure overlaps with the first light-emitting area.
