The invention provides a backlight module and a display device. The backlight module comprises a light source, a light-guide plate and a reflection layer. The light-guide plate is provided with a light-incident surface, a first light-emitting surface, three light-leaking surfaces and a second light-emitting surface parallel to the first light-emitting surface. The light source and the light-incident surface are correspondingly arranged. The reflection layer and the second light-emitting surface are correspondingly arranged. The backlight module further comprises light conversion layers arranged on at least one light-leaking surface and used for converting emergent light emitted from at least one light-leaking surface to white light. As a result, the color of emergent light emitted from at least one light-leaking surface is turn into white through color complementation such that leakage of blue light of the backlight module is effectively reduced. It is ensured that a large amount of light emitted from the first light-emitting surface of the light-guide plate is blue light. Blue light is further converted into white light so that luminance and color uniformity of the backlight module are improved.
