Backlight module and display device

The invention describes a backlight module and a display device, the backlight module comprises a light-emitting area and a non-light-emitting area surrounding the light-emitting area, and the light-emitting area comprises a central area and an edge area; at least part of the first substrate, the first light source and the quantum dot conversion layer are located in the light emitting area; the quantum dot conversion layer is located on the side, away from the first substrate, of the first light source in the direction perpendicular to the light-emitting face of the backlight module. The light supplementing assembly comprises a second light source and a light guide plate, and the light emitting surface of the second light source faces the light guide plate; the first light source and the second light source are different in light emitting color, and at least part of the light guide plate is located in the edge area. By arranging the light supplementing assembly, the light color of the edge area of the light e
