The present disclosure relates to a backlight module and a display device. The backlight module comprises a light guide plate and a light-emitting assembly configured to emit light rays and cause the light rays as emitted to be incident to the light guide plate in parallel. The light guide plate further comprises a light incident surface, a bottom surface, a light emitting surface on the top thereof, and at least one reflective sloped surface. The reflective sloped surface is positioned between the bottom surface and the light emitting surface, and an angle between the at least one reflective sloped surface and a plane of the bottom surface extending in a direction away from the light incident surface is less than 90°. The light incident surface is located on a side of the light guide plate.
